The principal mycotoxins risk factor is the weather; especially when there is rain and hot temperatures, which favor moisture development. Crop rotation and ploughing are beneficial strategies to decrease the risk of mycotoxins.  Some varieties of crops can be more or less prone to developing mycotoxins.

Mycotoxins can have an impact on animals : milk quality (Trials shows a decrease of 0,4% in Fat, 0,1% in Protein), mastitis, or reproductive problems. They increase the calving interval of 60 days, need 10% more inseminations, and increases veterinary costs by 10%.

The quantity of mycotoxin is increasing in the world, thus is a topic that we should all focus on. 

After observing a grain silo, it can be valuable to take a sample for laboratory analysis. If the analysis shows a crop is infected, the farmer can look for a Mycotoxin captor and be advised the next year about how to properly manage silage production. This product can help avoid using antibiotics on the farm (resulting in antibioresistance).  

TIMAC AGRO Technologies have the following effects:

– Trap and absorb mycotoxins

– Enable the biotransformation of mycotoxinswhich permits to reject them from the body.

  • Increase hepatic protection 
  • Boost ruminal efficiencyso animals are able to take in more nutrients from their feed.

    Up to 70-90% of mycotoxins can be managed using our solutions.

In recent years, industrial Sulphur emissions have been reduced, meaning crops receive less sulphur from their environment. It is becoming more and more important to bring additional S to crops. The same goes for grasslands.

Sulphur in grassland can be partly supplied through the mineralization of organic matter. However, mineralization may not be enough, and a lack of S may occur. Sulphur is essential for grasslands in many aspects:

  • Sulphur’s well-known synergy with N, increases N efficiency and thus increases the yield of the grassland
  • Sulphur is needed for bacterial activity, which is responsible for organic matter mineralization Sulphur protects nodules from nitrate fertilisation, which leads to a reduction of N symbiotic fixation
  • Sulphur is required in huge quantities by animals. The higher the sulphur content in the grass, the better it is for animals.
  • Sulphur improves the quality of proteins with a higher content of methionin, which is an essential amino acid for animals.

 That’s why S fertilization in grassland must not be neglected, and especially if the soil is prone to deficiencies (sandy and shallow soils, winter with heavy rainfall and runoff)

How to Prevent Fruit Splitting In Citrus

Physical appearance is an important factor to ensure commercial yield for citrus fruits, especially since 84% of them are consumed fresh. Their attractiveness is linked to their skin or peel (firmness, smoothness, gloss and color). Physiological disorders such as splitting and creasing increase financial losses.

10-35% of citrus display splitting or creasing disorders, which severely affects fruit quality and yield. This leads to financial losses between 9K to 13K €/ha

Splitting indicates a separation of the albedo (the white material under the outer peel) from the outer surface of the fruit. This internal damage is visible externally as an uneven appearance of the rind surface, and it can’t be reversed.

Different environmental parameters can cause creasing on citrus fruits : Light, temperature, nutrition (insufficiency or excess of N or K, lack of Ca), humidity… But those physiological disorders are usually associated with tree water status and soil moisture content.

When heavy rains happens after a drought period, the fruits that were under water stress absorb it very quickly, leading to rapid swelling which causes changes in the ultrastructure of the cell wall and cell loosening, thus resulting in fruit creasing or even fruit splitting. To fight this phenomenon, in addition to balanced nutrition, it is recommended to have an irrigation system that is able to prevent water stress, which might be complicated for a lot of climatic conditions. Another solution is to find a way to increase cell wall plasticity so that cell growth and cell extension can be promoted, which could also inhibit fruit creasing.

A classic solution can be the use of phytohormons like Gibberelin. They promote cellular division and is associated with growth. Even though Gibberelin treatments might improve the fruit quality, the possible restrictions related to this product (due to its pesticide registration) has led to the search for alternatives that improve the fruit setting and are compatible from an environmental and sanitary point of view.

There are TIMAC AGRO Technologies that have a double action to stop creasing even without phytohormones:
• This technology contains precursors of growth regulators
• It also contains messengers requested for the expression of these growth regulators

Therefore, applying such technologies can reinforce the plant’s ability for the biosynthesis of all the growth regulators that will influence the entire process of fruit production. It contributes to a balanced equilibrium between these substances, remaining under the natural regulation.

Improving how you manage your livestock effluents is a big economic and environmental challenge. Each step of the process needs to be consideredfrom the animal feed to spreading manure

Manure is a mixture of animal dung mixed with litter components (strawwood shaving…) stored on a platform or in the building. 

Slurry is composed of effluents with a very low quantity of dry matter and is stored in a pit. 

Both types of effluents can be produced by bovins, ovins, swine, and poultry, and each has different fertilizing capabilities.

The storage and management of effluents is not simple. Here are some frequently encountered difficulties :

     The stored manure is a heavy producttakes up spaceproduces strong odors and smells of ammonia. (NH3). Badly managed manure can : 

  • Be complicated to decompose
  • Be asphyxiating for the soil

    The slurry stock in a pit takes up a lot of space, and needs to be managed correctly because

  • It releases odors of ammonia and sulfur.
  • Creates a crust at the surface and which makes it complicated to handle and remove later on. 
    For both effluents, poor management creates poor compost. These effluents should be managed correctlybecause maximizing their fertility potential is essential for crops and pastures

How to Improve Soil Fertility

A deeper understanding of soil composition is essential in order to create optimized fertility programs. Among other factors observed through soil analysis, organic matter is a reliable indicator of soil fertility, as it affects physical, chemical, and biological properties of the soil

Organic Matter is essential for attaining healthy soil fertility.

 

 

Biological activity: most of the micro-organisms living in the soil need energy from the organic matter to be efficient and optimize their biological activity.

 

Nutrient availability: thanks to the micro-organisms, the fresh organic matter is either mineralized (1) into nutrients, directly available for plants (2) or transformed into humus (3), the most stable part of organic matter that plays an essential role on the soil structure and nutrient availability through time.

This humus is in turn mineralised in order to provide nutrients for the plants, we call it the second mineralization (4) and this process is much longer than the first mineralization mentioned above. At the same time, this humus binds to clay in order to form the well-known clay-humus complex (5). This complex catches nutrients (6) and prevents them from leaching and being blocked by other molecules, until it releases (6) them into the soil solution where plants can access nutrients.

 

pH regulation (7): The clay-humus complex also has a high-buffering capacity, trapping H+ cations that are responsible for acidifying the soil. Be careful: the cation exchange capacity of the complex is not unlimited and when more H+ cations become trapped, fewer essential nutrients for plants will be stored.

 

 Soil structure (8): the clay-humus complex also plays a major role on the soil structure as it

• allows the aggregation of soil particles in order to get a better porosity,

• limits the number of free particles (and so, limits the risk of beating),

• reinforces the soil resistance to compaction.

How do certain fertilizers impact soil pH?

Low calcium levels can lower pH. Calcium is a secondary element that is required in high quantities. It also plays a role in increasing or maintaining a soil’s pH levels, and its losses must be regularly compensated.

On average, a field loses 400kg to 700kg of calcium per ha per year. Calcium loss is the first step towards unbalanced pH levels. Calcium levels drop when crops use up the nutrient, through leaching, or from the use of fertilizers. Fertilizers have a decalcifying effect in three ways:
• They increase yield and the nutrient is taken up by the plants;
• NH4+ and K+ ions create a movement of the ions Ca2+ from the humic-clay complex towards the soil solution ;
• Nitrification is an acidifying reaction : The use of fertilizers containing Ca reduces the acidifying and decalcifying effects of ammonium-based fertilizers. Even if the total quantity of Ca supplied per ha is low, the effect of Calcium-rich fertilizers has proved to be very efficient on micro pH (found in the rhizosphere), which is extremely important for crops.

In the end, this association of Ca and N fertilizers can maintain soil pH, boost nitrifying bacteria and increase NUE. Source: Soltner, 2014

Tomatoes are consumed all around the world for their nutritional and organoleptic qualities. 25% of the world production is for the processed market  (2002). According to the requirements of the processed tomato market, growers need to focus on yield and physical quality.

Fruit development is an important concern regarding yield and fruit quality in processed tomatoes.

The first two weeks after fruit set is the phase of cell division with slow growth, then cell expansion with rapid fruit growth.

Cell division and expansion happens in the plant cell wall composed of many elements, in particular hemicellulose xyloglucane and pectin. Both allow the reshaping of the cell  wall and therefore fruit development :

  • Hemicellulose interacts with cellulose microfibrils  and enables the cell to change its shape during growth and development (Hayashi and Kaida 2011)
  • Pectin controls the permeability of cell walls and is involved in regulation of ion transportation (Voragenet al 2009) which will determine important parameters such as texture and firmness (Brummell 2006; Jarvis et al 2003).

With the application of our technologies, we saw a 20% increase in yield and fruit size. This coincided with a higher density of pectins and xyloglucans in the cell walls.

Ruminants can be easily impacted by heat stress. It does not take extremely high temperatures for your animals to experience stresses that can have severe health consequences. In addition to heat, it is also highly important to consider humidity when determining the level of stress your animals might experience.

Summer is here, here’s a table to help you determine your cattle’s level of stress.

Source: Habeeb, Alsaied & Gad, Ahmed & Atta, Mostafa. (2018). Temperature-Humidity Indices as Indicators to Heat Stress of Climatic Conditions with Relation to Production and Reproduction of Farm Animals. International Journal of Biotechnology and Recent Advances. 1. 35-50. 10.18689/ijbr-1000107. 

Most of the time, heat stress occurs during summer, that is why it is a crucial period for farmers to implement strategies to mitigate the negative effects of these warmer months. 

  • Decrease in dairy production

Milk production often decreases during summer due to the high temperatures. This reduction in milk production can reach 1 to 4 kg of milk per cow (0.28 kg/h of loss during light heat stress and 0.303 kg/h of loss for moderate heat stress). The decrease of milk production can also be the result of mastitis, which occurs when white blood cells are released into the mammary gland. 

  • Decrease of reproduction

Heat stress can cause hormonal disruptions, energy deficits and oxidative stresses. Oxidative stress  can result in non-fertilizing insemination and embryonic mortality.

  • Risk of acidosis

From 25°C the biological systems of cattle make an effort to avoid increasing their internal temperature; by decreasing rumination and decreasing ingestion. As cows ruminate and swallow less, a decrease of saliva occurs which cause an overproduction of acids leading to acidosis.

  • Risk of  lameness

Risk of laminitis and lameness increase with heat stress. Cows are in tougher environmental conditions and are more prone to developing physiological disorders.

That being said,  there are several strategies farmers can implement through proper nutrition and feed supplements that help reduce the negative effects of heat stress.

50% REDUCTION OF DUST EMISSIONS AT THE LODOSA FACTORY IN SPAIN

At the Lodosa site in Spain, new facilities have been brought into operation in the granulation workshop. This new equipment ensures the complete sealing of several belt conveyors and their associated dust removal systems.

They add to a first investment phase involving the installation of a baghouse filter with a capacity of 95,000 m3/H to clean the cooling fluidised bed. This enables the site to continue to reduce dust emissions drastically.

At the industrial estate site in Saint-Malo, France, a new baghouse filter has also just been installed to process the air released from the drying operation using 600 bag filters. This dust-filtered air is then directed to a spray tower inaugurated in September 2020.

Not only does this equipment contribute to a significant reduction in material loss, but it also ensures energy optimisation. Besides, it is of great interest in the recycling of our process water. All of our sites are continually seeking to make our workshops even cleaner and to improve their operations.
