Potassium fertilizer

Potassium is one of the main sources of plants root nutrition. Its lack of soil leads to considerable decrease in productivity and quality of agricultural production, lowers resistibility of plants to illnesses drought resistance.
In  the Republic of Armenia delivery to an agriculture potassium fertilizers is extremely limited, and available only chlorine - containing fertilizer. A removal of potassium from the soil with crop much higher than the parish, which has led to significant depletion of the soil.Furthermore it is widely-known that аccumulation of chlorine in the soil has  detrimental effect on fertility and it is pernicious for crop. Rhyolite-dacite tuffs of  Tashir's (Kalinino) deposit passing special hydro-thermal processing jointly with calcium oxide form the hydrosilicate, which interacts well with Solution of PATERMAN, and this is the classical proof of the fact that will be assimilated by plants.
Agrochemical estimation of fertilizer based on RDT according to the numerous field tests carried out in  the Republic of Armenia  and Russian Federation, on different soils (noncarbonate, weakly-carbonate, acid,  chernozem etc.) and on different  cultures (wheat,  barley,  oats, pea, potatoes, cabbage, sunflower, tomatoes, fruit trees  etc) confirm  the efficiency of its application.
Field trials in different regions of RA showed the greatest effect from the use of potassium fertilizer on the basis of RTD in Aparan-Razdan, Lori Pambak, Shirak zones, Ashtarak, Artik and Stepanavan regions, in  Sevan basin, Lori marz.

AGROCHEMICAL TEST

1. Armenian Agricultural Academy (responsible App. Yeritzyan S.K. 1986-1987)
Field experiments were laid with spring berley and apple tree in the state farm of Karby village(Ashtarak region), with corn silage in Voskehat’s experimental farm (Echmiadzin area), with winter wheat in the state farm of Ddmashen(Sevan region).
2. Scientifically - research institute of soil science and agrochemistry, and State Agricultural Committee RA  (responsible App. A.S. Khachatryan, 1989 -1991)
Field experiments were laid with potatoes and corn for silage in mountainous, leached chernozem of Stepanavan region(Village Vardablur),Tashit region(v.Norashen, Medovka) and with  potatoes and cabbage in the in inundated and meadow soils of Acarat (Marz Gegharkunik).
AGRICULTURAL Experiment Station of Solikam,  Perm province of Russian Federation(responsible App. GN Belyaev 1989 1991)

Field experiments were put on sour poor by magnesium sod-podzol sandy and sabulous to soil of Predural which is typical for the  northeast extensive region of the European part of Russia (Nonechernozem zone).

As a result of studying the properties of potassium fertilizer on the basis of PDT determined that due to the porous structure of the fertilizers have a greater water capacity and ability to absorb ions with positive and negative charges, thereby improving water treatment plants and reduced losses of nutrients from the soil

The Generalised results of tests

1. The crop increase (potatoes, cabbage, corn, wheat, barley, apples, etc.) on average by 20-40%
2. Improving the quality of the agricultural products (increase of starch content, dry matter, vitamin C and reduce the number nitrates in potato tubers 4-5 times)
3. Prolonging effect of fertilizers, which gradually decaying in the soil solutions gives nutritious components within 2-3 years
4. .Increase of a moisture capacity of soil to 500-580 %
5. Neutralization of soil acidity
6.  The prevention of stem drowning of grain crops
7. The ability to absorb the positive and negative ions from the soil, preventing washing away from  soil of nutrients and ions, first of all, ammonia and nitrate nitrogen
8. Improving the general ecological conditions and quality of concrete production in comparison with the use of highly concentrated soluble fertilizers like potassium chloride or other

Manufacture of fertilizers on the base of "Vanadzor-Khimprom, given the location of the mine, 60 km from Vanadzor, greatly simplifies the delivery of raw materials and cheaper transport costs, which will ultimately affect the low-cost of fertilizer. Availability of necessary equipment and highly skilled professionals helped to create waste-free technology with international ecology requirement.
Small capital investment will increase production capacity in the short term to 50,0 thousand tons / year.
Of particular note is the use of only local raw materials, complete independence from the supply from abroad, which would make a certain kind of food security program of the Republic of Armenia.
Soil-based fertilizers RTD is recommended in the spring before planting soil under cultivation in the autumn when soil preparation for sowing of winter crop.
The optimal amount of fertilizer introduction into soil 500kg for 1 hectare.The  Production price it will be considerable below the prices of fertilizers imported from abroad. With a manufacture exit on a designed capacity (3-4,5 thousand tons a month) production cost will decrease.
Works on creation of the complex fertilizers containing besides  Ca, K, Fe and microquantity of other elements enriched P, Mg and organic components are simultaneously conducted. It will allow to spend differentiated use of fertilizers on various soils.
In the long term need to test fertilizer-based RTD in saline and acidic soils, where the expected efficiency will be essential.
