Brazil is one of the largest grain producers in the world. Grain production in Brazil, from the 2014/2015 harvests, is estimated at 200.7 million tons. Of Brazil’s harvested area, 49% is intended for growing soybeans. This is the most important grain in Brazil’s trade balance.

 

The benefits that TK47 and Super Greensand offer for grain cultures are:

  • Increases the availability of phosphorus in the soil
  • Has no salt effect nor chlorine content
  • Optimizes management: allows potassium to be applied in pre-planting and eliminates the fertilizer re-application
  • Increases crops resistance against pests and diseases
  • Reduces plant transpiration rate thus reducing water loss
  • Contains the elements sulfur, phosphorus, manganese, zinc, copper and cobalt in small amounts
  • In case of drought and loss of crop, the potassium remains in the soil for the next crop
  • Improves cellular structure of the plant
  • Benefits the process of photosynthesis
  • Reduces the impact of drought, heat, cold, soil salinity and heavy metal toxicity

 

In addition to all the benefits mentioned above, TK47 offers even more advantages for grain cultivation:

  • Corrects soils pH without releasing CO2
  • Releases potassium in a controlled manner according to the needs of the plant

Results of TK47 on Soybeans 

A study was conducted by the Federal University of Lavras (UFLA) to evaluate the agronomic efficiency of TK47, compared to KCl, on soybean crops. The results demonstrated TK47’s superiority to KCl in the production of dry matter in the aerial part (DMAP), total dry matter (TDM), dry matter pod (DMP) and dry matter grain (DMG). The percentage of grains that were not withered was similar, with no statistical difference.

 
[1] Dry matter is the fraction of food without its natural moisture, in which nutrients are contained (carbohydrates, proteins, minerals, etc.) 
DMAP - dry matter production of leaves and stems
TDM - sum of the dry matter of aerial parts and roots
DMP - dry matter production of the pods
DMG - production of grain dry matter 

 

Results of Super Greensand on Millet

In 2012, in partnership with the Federal University of Uberlândia (UFU), a study was conducted to evaluate the agronomic efficiency of Super Greensand on millet. The control group received no potassium, whereas the treatment group received two doses of K2O of 20g and 40g from Super Greensand. In order to evaluate the residual effect of potassium, two consecutive cycles of millet were planted. Super Greensand was applied to the first cycle only.
