THE USE OF ZEOLITE IN RICE AND THE USE OF NEW ZEOPROFIT FERTILIZERS.
Rice is a basic food for about half of the earth's population. The average yield is currently at 400-600 kg / acre. Some varieties have yielded more than 1000 kilograms / acre.
The general rules for the fertilization of wheat also apply to rice. However, the specific cultivation conditions created in the rice fields must be taken into account here.
Rice grows better in soils flooded with water. Soils such as: permeability and redox potential of the soil play an important role.
Rice paddles must have, on the one hand, a low permeability to retain the water and, on the other hand, they can supply the radish with air. Thus, it is desirable to have an impervious layer (natural or artificial) at a depth of about 20 cm, but the surface soil must be lukewarm.
Reducing conditions have the effect of releasing manganese and iron (in their divalent form). Even some of the phosphorus is released when the trivalent (phosphate) iron becomes bivalent.
A problem in this case can be brought about by the reduction of sulphates (eg NH4SO4 to produce hydrogen sulfide H2S) Hydrogen sulfide is phototoxic, but FeS can be formed as sediment as iron, thus limiting the phytotoxicity of H2S, provided that there is soluble iron in our soil.
To avoid phytotoxicity, it is advisable to use urea instead of ammonium sulphate and even cheaper NH4Cl used in the Brazilian and Far East rice fields (Asia).
Because nitrates in this environment are easily deodorized, we must prefer ammonium fertilizers and place them in the reduction zone before sowing (plowing or special machines). Even surface lubrication should be done with ammonium fertilizers.
The requirements of rice in F-K fertilizers are: 10 kg of P2O5 and 15 kg of K2O to produce 1000 kg of fruit per acre.
The amount of nitrogen required depends on its degree of utilization and is often <50% (5-15 kg N / ha for average yield in 1-4 doses). The distribution of N in installments is intended to meet the critical stage needs and limit losses. Decisive is a dose in the formation of the inflorescence.
Excessive N-lubrication may, however, have adverse effects (crease, loss of strength, etc.).
N-phase fertilization improves the quality of rice, which is of great importance for countries where rice is the main food of their inhabitants.
A serious problem with TORFOVIT in rice cultivation is the continuous presence of water in the field, making it easier to apply. One way is to supply a motorized back sprayer that can spray the spraying liquid even 20-25 meters and walk around the embankments to disperse TORFOVIT in the crop.
Another way is the Asians who cultivate rice using the technology of TORFOVIT and have ample experience. They recommend the construction of a fermentor at the entrance of the pan to provide the crop with TORFOVIT. A dredger fertilizer is nothing but a dirt tank at the entrance to the water in the field. The fermenter for a 10-acre pan should have the following dimensions: depth 1.5 meters, width 3 meters and length 6 meters. If your field is smaller, adjust the dimensions accordingly by keeping the depth constant.
The fermenter is filled up to one meter with poultry manure fermented with TORFOVIT or generally with organic ingredients that you have fermented. The remaining half-meter of the tank-fermenter is filled with water. Add 60 liters of TORFOVIT and allow to ferment with organic material for 5-8 days. Then we drain the water, which as it enters the pan to water the rice takes along with it the TORFOVIT which spreads throughout the cultivation. From time to time, stir the water in the fermenter to pick up the organic load inside.
The water that leaves the fermenter and enters the rice crop is black because it contains the metabolites, such as amino acids, polysaccharides, organic acids, antioxidants and nutrients.
A disadvantage of the fermentor is that it requires its construction next to a road to be able to supply with organic material.
After harvesting the rice, take care to shred the straw with a shredder and sprinkle the straw with TORFOVIT solution at 2 liters per acre with zeolite (2 pounds / 100 liters of water). In this way we will have rapid degradation of straw, an increase in organic matter and we will have no problems in the next year with straw floating in the pans.
