Legumes

After cereals, legumes are the second most popular. This includes table, fodder and industrial crops: green and white beans, green and grain peas, lentils, chickpeas (white peas), soybeans and many others. Peas, chickpeas and lentils are among the cold-resistant crops of a long daylight hours, and southern legumes – soybeans and beans – are among the more heat-loving short-day crops. All legumes need crop rotation and cereals are considered the most favorable predecessors.

Peculiarities

Legumes are very susceptible to nitrogen, thanks to nitrogen fertilizers protein synthesis occurs, which all legumes are rich in. The first application of SatoSoil® Biome or SatoSoil® Prima improvers is carried out in autumn when plowing to preserve the fertile soil layer after predecessors.

Application of organic fertilizers – manure, compost and vermiculite – mixed with SatoSoil® conditioners, which suppress the overly bioactive green manure environment, is recommended.

If the agrochemical composition of the soil requires it and pre-sowing inoculation of seeds is not carried out, the starting biostimulant granulate SatoGrowht NPK® is applied. Pre-sowing soil preparation includes the reapplication of SatoSoil® improvers and SatoGrow® organo-mineral biostimulants.

For pre-sowing treatment, it’s recommended to use a liquid disinfectant Sato® Seeds, which improves the immunity of seeds and seedlings and protects sprouts from pathogens, ensuring simultaneous seedlings. When applying bio-inoculants, a compatibility check with Sato® Seeds is required to avoid the effect of suppressing beneficial rhizobia bacteria in root nodules.

During the growing season, legumes have many natural pests and pathogens. To enhance the legumes’ own defenses, the silicon-containing composition SatoHum® SiO is used, which promotes the production of specific phytohormones and strengthens the stress resistance of plants before parasite attacks.

Signs of nutrient deficiency in legumes

yellowing of leaves and pods - lack of nitrogen;
a quick green mass gain, weak ripening of the pods, darkening of the leaves, twisting the leaves down - an excess of nitrogen;
brown edges on leaves, bluish tint on leaves - lack of potassium;
wrinkled leaves, interveinal chlorosis - magnesium deficiency;
reddening of the leaves, dark and stunted leaves and shoots - phosphorus starvation;
yellow spotting on the leaves - an excess of phosphorus;
light or brown spots on the leaves - lack of magnesium or manganese;
blackening of shoots - boron deficiency.
