Biochar application to the soil can improve quality and nutrient leaching loss from swine manure adapted soils. Our working hypothesis was that biochar-incubated with could be a better amendment than conventional application. The manure-biochar would decrease increase plant-available nutrients. study objectives were 1) assess physicochemical properties of mixture after lab incubation 2) evaluat...

Indaziflam, a new alkylazine herbicide that inhibits cellulose biosynthesis, is under current development for soil applications in perennial crops and nonagricultural areas. Sorption and desorption of indaziflam in six soils from Brazil and three soils from the United States, with different physical chemical properties, were investigated using the batch equilibration method. Sorption kinetics d...

The relationship between environment and abundance of rhizobia was described by determining the populations of root nodule bacteria at 14 diverse sites on the island of Maui. Mean annual rainfall at the sites ranged from 320 to 1,875 mm, elevation from 37 to 1,650 m, and soil pH from 4.6 to 7.9. Four different soil orders were represented in this study: inceptisols, mollisols, ultisols, and an ...

Soil water and temperature are important factors to reflect variations in soil heat flows especially for tillage systems. The objective of this study was evaluate the performance CoupModel predicting effect practices on processes conventional (CT) no-tillage (NT) systems with straw mulching semi-arid high-latitude Mollisols northeast China. This model calibrated evaluated a three-year experimen...

Pedodiversity is considered the cornerstone of biodiversity. This work aimed to (1) assess pedodiversity according vegetation, topographic factors, and lithology (2) identify major soil-forming factors on soil organic matter (SOM) stock at a 0–30 cm depth. These goals were reached using data from 147 georeferenced profiles distributed along 400–1000 m (≤1000) 1000–2134 (>1000) altitudinal gr...

Information about the hydrology of oak ecosystems of the southwestern United States and northern Mexico is lacking (Lopes and Ffolliott 1992, Baker et al. 1995) even though the woodlands and savannas cover more than 31,000 square miles. These ecosystems generally are found between 4,000 and 7,300 feet in elevation. Precipitation occurs in the winter and summer and averages between 15 and 20 inc...
