Phosphate fertilizers were first implicated by Schroeder and Balassa in 1963 for increasing the Cd concentration in cultivated soils and crops. This suggestion has become a part of the accepted paradigm on soil toxicity. Consequently, stringent fertilizer control programs to monitor Cd have been launched. Attempts to link Cd toxicity and fertilizers to chronic diseases are common. A re-assessme...

Analysis of heavy metals in top soil samples from Nzoia sugarcane farms in Western Kenya found elevated levels of heavy metals in the soils with mean concentrations (mg kg⁻¹ dry weight) of 142.38, 59.12, 73.35, 116.27, 409.84 (dry season) and 144.22, 50.29, 72.14, 158.81, 368.83 (wet season) for Cr, Pb, Cu, Zn and Fe, respectively, compared with a control soil sample from an adjacent field wher...

Abstract Although onion, Allium cepa L., production has been enhanced by the addition of organic matter to soil, other reports indicated no effect. In this study, onion plots (var. Sweet Sunrise) were treated with conventional fertilizer, composted sugar mill ash and vegetative yard waste, or fertilizer + compost. Measurements during two consecutive growing seasons in Lower Rio Grande Valley Te...

In order to study the effect of different levels of the manure and foliar application of Zn and Mn fertilizers on the quantitative and qualitative yield of soybeans (var. Williams), a factorial experiment was conducted in a randomized complete block design with three replications in 2012. Treatments involved three levels of fertilizer: manure (zero as control; six and 12 t/ha), two lev...

Zinc (Zn) is increasingly recognized as an essential trace element in the human diet that mediates a plethora of health conditions, including immune responses to infectious diseases. Interestingly, geographical distribution dietary Zn deficiency overlaps with soil deficiency. In South Asia, malnutrition high due excessive consumption rice low content. Interventions such diversification, food fo...

An objective of study effect on inorganic sources NPK and Zn fertilizers soil health with the experiment was laid out in Randomized Block Design three levels (00%, 50% 100%), Zinc 100%) Recommended Dose fertilizer applied all treatments. The result showed that properties, growth yield chickpea were significantly affected by application Zinc. highest observed T9 (100%NPK +100% Zinc), followed T8...

A system of routine foliar analysis of sugar cane for N, P, K, Ca, Mg and S is discussed which, together with subsequent field soil analysis, is used as criteria for fertilizer recommendations on the estates and privately-owned sugar farms in the Rhodesian Lowveld. The sampling techniques and analytical methods described are reasonably rapid, economical and accurate. Furthermore, they do not re...
