The Differentiated Fertilization Effect of Potato Production on a Gleisol Soil in Transilvania Plain
Year: 1970
Type: article
Abstract: SUMMARY The paper presents, on the base of experimental fie ld and analytical results, the effect of some differentiated fertilization systems (organic- mineral, complex mineral and foliar), on potato culture on a gleisol, considered with an ave rage yield capacity for agricultural plants. The yield results (of Redsec variety) highlight, fo r two experimental years, the effect of some complex foliar combinations (with NPK), sufficiently agrochemically balanced with a predominance of the nitrogen nutritive ratio. These foliar combinations are more efficient in the case of potato crop than in other field plants, an accountable phenomenon by the soil yield capacity and last, but not least by the potato sp ecificity, as concerns the radicular system biology that establish a higher dependence of this crop on the foliar applied fertilizers. The same yield results maintain high and constant yield s at the interactions and organic-mineral application of the fertilizers that confirm first o f all the organic resources effect in the nutritive maintenance of this culture. In the case of organic-mineral fertilization, interactions become net superior to the variants by which manure provides the organic constituent compared to the compost proceeded from mushroom culture technology, the last being better represented in cellulose and vegetal residues and b eing less complex than manure. In the context of experimented differentiated ferti lization systems, application of NP complex fertilizers, without organic support, reali zes lower yields. Analytically speaking, all fertilization systems es sentially alter the relevant indices of soil fertility, assessing as higher durable effect the interventions with organic resources, which can be involved in the yield and soil fertility sta bility, especially in the content economy of organic matter.
