A three-year (2006-2008) field experiment was conducted at Swift Current and Star City in Saskatchewan to determine the short-term in-fluence of land-applied anaerobically digested swine manure (ADSM)...
Nitrogen rate trials are often performed to determine the economically optimum N application rate. For this purpose, the yield is modeled as a function of the N application. The regression analysis pr...
With increasing human population against declining staple food crop yield trend, food insecurity is inevitable. Soil fertility problem has been identified as a major factor hindering maize productivit...
This study outlines the long-term trends of fertilizers consumption in the Czech Republic and Poland and their impact on actual yield development of main crops for the period 1986-2005. In both countr...
Building from the perception that farmers have an intimate knowledge of their local environment, production problems, crop priorities and criteria for evaluation, an on-farm experiment was conducted w...
Fertilizer application is one of the most important operations in agricultural production. Traditionally, fertilizer is applied onto the whole farmland regardless of the variations across the land.
An assessment of fertilizer use and other integrated practices was carried out with two hundred farmers selected by stratified random sampling from twenty villages in Kano and Katsina States of Nigeri...
Rice varieties derived from mutants with various kinds of seed protein components such as low glutelin or 26k-Da globulin deficiency were grown in different fertilizer conditions. The results of analy...
Carbonized organic materials have not traditionally been applied to grain legumes such as soybean (Glycine max L. Merrill) and cowpea (Vigna unguiculata L. Walp) although the potential for favourabl...
A field experiment with winter wheat (Triticum aestivum) on Orthic Luvisol was conducted for a period of eleven years. This study gives the ground to establish correctly the fertilizer rates, especial...
The objective of the study was to show the possibility and feasibility of the application of mathematical planning for the determination of the optimum structural parame- ters and bulk density of the ...
The treatments were fitted in a split plot design replicated thrice. The results of the experiments revealed that transpiration rate increased with decrease in plant population. Nutrient management pr...
Influence of dynamical factors on safe work with a fertilizer spreader.
A Bulgarian project at Maritsa East power station demonstrated the proper transformation of air pollutants (SOx and NOx) into nitrogen fertilizer. Although this technology has not been put into practi...
