Does Phosphate Affect Soil Sorption and Degradation of Glyphosate? – A Review
Glyphosate is worldwide the most used herbicide because it is an efficient weed killer with favorable environmental and toxicological properties such as very low human and animal toxicity. Chemically, glyphosate is a phosphonate, i.e. it resembles phosphate. Consequently, glyphosate is strongly sorbed by the same soil minerals as phosphate, especially aluminium and iron oxides, allophane/imogol...
متن کاملCompetitive sorption between glyphosate and inorganic phosphate on clay minerals and low organic matter soils
Inorganic phosphate may influence the adsorption of glyphosate to soil surface sites. It has been postulated that glyphosate sorption is dominated by the phosphoric acid moiety, therefore, inorganic phosphate could compete with glyphosate for surface sorption sites. We examine sorption of glyphosate in low organic carbon systems where clay minerals dominate the available adsorption sites using ...
متن کاملIntegrating soil conservation practices and glyphosate-resistant crops: impacts on soil.
BACKGROUND Conservation practices often associated with glyphosate-resistant crops, e.g. limited tillage and crop cover, improve soil conditions, but only limited research has evaluated their effects on soil in combination with glyphosate-resistant crops. It is assumed that conservation practices have similar benefits to soil whether or not glyphosate-resistant crops are used. This paper review...
متن کاملEffect of soil aeration and phosphate addition on the microbial bioavailability of carbon-14-glyphosate.
The adsorption, desorption, degradation, and mineralization of C-glyphosate [-(phosphonomethyl)glycine] were examined in Catlin (a fine-silty, mixed, superactive, mesic Oxyaquic Argiudoll), Flanagan (a fine, smectitic, mesic Aquic Argiudoll), and Drummer (a fine-silty, mixed, superactive, mesic Typic Endoaquoll) soils under oxic and anoxic soil conditions. With the exception of the Drummer soil...
متن کاملImpacts of Steel-Slag-Based Silicate Fertilizer on Soil Acidity and Silicon Availability and Metals-Immobilization in a Paddy Soil
Slag-based silicate fertilizer has been widely used to improve soil silicon- availability and crop productivity. A consecutive early rice-late rice rotation experiment was conducted to test the impacts of steel slag on soil pH, silicon availability, rice growth and metals-immobilization in paddy soil. Our results show that application of slag at a rate above higher or equal to 1 600 mg plant-av...
