SALA�, P.: Slow-release fertilizers and possibilities of their utilizing in nursery. Acta univ. agric. et silvic. Mendel. Brun., 2004, LII, No. 2, pp. 155-164 Reserve, slow-release fertilizers (SRF) enable to simplify the whole system of plant nutrition and fertilisation. Tabletted fertilizers of the Silvamix series represent a prospective product of Czech provenience. At our university, these ...

The availability of orthophosphate (Pi) is a key determinant of crop productivity because its accessibility to plants is poor due to its conversion to unavailable forms. Weed's competition for this essential macronutrient further reduces its bio-availability. To compensate for the low Pi use efficiency and address the weed hazard, excess Pi fertilizers and herbicides are routinely applied, resu...

Despite extensive literature both supporting and critiquing the Green Revolution, surprisingly little attention has been paid to synthetic fertilizers' health and environmental effects or indigenous farmers' perspectives. The introduction of agrochemicals in the mid-twentieth century was a watershed event for many Mayan farmers in Guatemala. While some Maya hailed synthetic fertilizers' immedia...

A greenhouse pot experiment was conducted to evaluate the effect of phosphorous (P) fertilizers application to an alkaline calcareous soil on the water use efficiency (WUE) of lettuce cultivar "robinson" of iceberg type. Head fresh and dry weights, total water applied and WUE were affected significantly by the P fertilizer type and rate. P fertilizers addition induced a significant enhancement ...

Bu çalışma, kimyasal ve organomineral (leonardit hayvansal kaynaklı) gübre ile farklı miktarlarda fosfor uygulamalarının silaj mısırın verimi, besin element içeriği fosforun alım etkinliği (FAE) üzerine etkilerini karşılaştırmak amacıyla tarla koşullarında yürütülmüştür. Hafif alkalin reaksiyonlu, düşük organik madde içeriğine sahip alanda tesadüf blokları deneme desenine göre üç tekerrürlü ola...

The use of a soil fertiliser results in high, good quality yields. most widely used fertilisers are mineral or organic, but there is increasing attention on organomineral produced from sewage sludge. These contain beneficial components which may improve fertility and thus plant productivity, some concerns associated with their application due to composition. Using short-term pot experiment the ...

The following literature review explores the links between the use of macroand micronutrient fertilizers and human nutrition. The review focuses on the academic literature covering the effects of fertilizers on plant and human nutrition in areas with nutrient deficient soils, with a particular emphasis on South Asia and Sub-Saharan Africa. Additionally, the review identifies a few of the primar...

This publication presents the results of studies bottom sediments (sapropels) lakes in North Kazakhstan region. The purpose this study is to identify possibility using sapropels from region obtaining innovative fertilizers for organic farming. For purpose, geoinformation technologies, field research, statistics, and chemical chemical-analytical methods were used (automated spectrometric segment...
