8. MAGNESITE FERTILIZER TU 2189-00281950-001-99.

1. Natural magnesite fertilizer for all agricultural crops. It is the best of all magnesite fertilizers known. It contains such microelements as copper, zinc, cobalt, manganese and iron. Small amount of talk is added to make the soil lighter. Magnesite is characterized by its neutralizing ability, exceeding that of limestone mill, i.e. it is highly effective acidic soil neutralization..

2. 100 kg of magnesite is added to soil per every hectare while ploughing or while planting crops to slots - this norm is for cereal crops. For potatoes and other vegetables 200 kg per every hectare should be added. The enclosed instructions will contain the norms for all the agricultural crops.
Using magnesite you get 40% harvest increase, the keeping quality is improved as well as nutritive value. This is achieved by increased saccharinity, starchiness, oil content, and the content of ascorbic acid. Vegetable scab possibility especially that of potatoes is eliminated. Crops ripening time is diminished.
