This article presents the results of physical and chemical properties humic simple superphosphate obtained by decomposition ordinary phosphorous flour Central Kyzylkum with sulfuric acid addition oxidized coal from Angren deposit hydrogen peroxide. The distinctive characteristics are shown in comparison without coal.

Excessive fertilization with organic and/or inorganic P amendments to cropland increases the potential risk of P loss to surface waters. The objective of this study was to evaluate the effects of soil test P level, source, and application method of P amendments on P in runoff following soybean [Glycine max (L.) Merr.]. The treatments consisted of two rates of swine (Sus scrofa domestica) liquid...

The study outlines a novel and traceable procedure for inactivating zinc polluted soil (an Anthrosols) adjacent to former (Zn) ore mine “Orzel Bia?y” in Bytom (Poland), where the total content of Zn amounted 3988.0 mg kg?1. This pollution level initiated an inactivation process involving two natural mineral sorbents, i.e., zeolite (Z) bentonite (B), as well their five blends (ZeoBen) expressed ...

Phosphorus fertilization and liming are alternatives used to increase forage production in Southern Brazil grasslands (Pampa grasslands) avoid its replacement by cultivated exotic crops. However, changes natural soil fertility can significantly affect the equilibrium of vegetation communities. We hypothesized that triple simple superphosphate limestone using would lead greater dry matter botani...

Agricultural intensification is associated with the use of great amounts of agrochemicals that may result in the accumulation of metals in soils, and –subsequently—agricultural products and food chain. Nowadays, this is a major concern for many Iranian agricultural products, necessitating scientific researches on the issue. Therefore, the present study has been conducted to evaluate the level o...
