Monitoring the state of the insurance of soil with the main total forms and mobile nutrients under the influence of fertilization, in the conditions of the Vineyard Iasi

Abstract

The problem of vineyards fertilization is especially complex because of the great amuont of agents that interfere. Fertilization, in nowadays technical progress, must amplify and intensify the productive capacity of fertile vineyards in correspondace with the effort-effect-efficiency relation avoiding the risk of pollution of the crop or the environment. The influence of fertilization chemical on certain indicators of basic soil fertility (Nt, P-AL, K-AL), appears clearly in the conditions of experimentation and reflects the status of cultivation and fertility status of the soils with vocation wine. From this point of view, use of doses moderate fertilizers, administered especially in complex ternary (NPK), led in the study undertaken at the improving regime nutritional variety Aligote and respectively to a stabilization of its in the field of optimum on the entire range of vegetation analyzed.
