Soil Amendments and the Rhizosphere Effect

Zentralblatt für Bakteriologie, Parasitenkunde, Infektionskrankheiten und Hygiene. Zweite Naturwissenschaftliche Abteilung: Allgemeine, Landwirtschaftliche und Technische Mikrobiologie, 1975
Summary Occurrence of bacteria ammonifiers, and nitrifiers in rhizosphere and non-rhizosphere soils of wheat and soybean, grown in unamended soil, soil amended with root exudates, urea or ammonium sulphate was studied. In unamended soil, both plants stimulated bacteria and ammonifiers in their rhizospheres on the 10th, 20th, and 30th day after sowing.

Soil Amendment: A Technique for Soil Remediation of Lactofen

Bulletin of Environmental Contamination and Toxicology, 2007
Lactofen, a member of the diphenyl ether chemical family, shows great potential for the control of broadleaf weeds associated with leguminous crops. It presents a high degree of selectivity when applied post-emergence to soybean and peanut crops. This paper presents the persistence of lactofen under a soybean crop under various conditions, including ...

Soil Amendments for Mitigation of Compacted Soils

Low Impact Development 2010, 2010
Traffic during construction has been shown to compact soils resulting in reduced porosity and infiltration rates and increased runoff. In agricultural settings soil amendments have been found to counter-act compaction effects. To evaluate the mitigation potential of two soil amendments (compost and fly ash) and determine potential water quality impacts,

The Influence of Soil Decompaction and Amendments on Soil Quality

Arboriculture & Urban Forestry, 2023
Abstract Urban soil is often compacted during anthropogenic activities, which presents a challenging substrate for tree growth. Two techniques for decompacting soils (air spading and vertical mulching) were evaluated alone and in combination with the soil ...

Phosphate Adsorption by Ferrihydrite‐Amended Soils

Journal of Environmental Quality, 2005
ABSTRACTNew technology and approaches for reducing P in runoff from high sediment yield areas are essential due to implementation of increasingly rigorous water quality standards. The objectives of this research were to characterize ferrihydrite (Fe5HO8·4H2O) in terms of its ability to adsorb P from soil solutions and relate its P adsorptive capacity ...

Soil enzyme - soil amendment interactions.

2023
A simple, rapid and reproducible method of assaying 1,3-β glucanase activity in soil has been developed, using laminarin as a substrate. It was founded upon a detailed analysis of the factors involved such as: quantity, type and age of soil; choice of: buffer, substrate concentration, microbial inhibitor, pH, temperature and incubation time, and ...
