Bacterial Indicator of Agricultural Management for Soil under No-Till Crop Production
The rise in the world demand for food poses a challenge to our ability to sustain soil fertility and sustainability. The increasing use of no-till agriculture, adopted in many areas of the world as an alternative to conventional farming, may contribute to reduce the erosion of soils and the increase in the soil carbon pool. However, the advantages of no-till agriculture are jeopardized when its...
متن کاملTopography Mediates the Influence of Cover Crops on Soil Nitrate Levels in Row Crop Agricultural Systems.
Supplying adequate amounts of soil N for plant growth during the growing season and across large agricultural fields is a challenge for conservational agricultural systems with cover crops. Knowledge about cover crop effects on N comes mostly from small, flat research plots and performance of cover crops across topographically diverse agricultural land is poorly understood. Our objective was to...
متن کاملChemical attributes of soil under no-till farming affected by crop systems and fertilization sources
Crop systems and fertilization sources can affect the chemical properties of the soil and, consequently, its fertility. With the aim of evaluating the effect of such management practices, soil samples collected at 0.0-0.10; 0.10-0.20; and 0.20-0.40 m in depth were collected and analyzed in the second year of an experiment installed in 2006 in a Rhodic Hapludox under no-till farming, located in ...
متن کاملInfluence of Compaction Condition on the Microstructure of a Non-Plastic Glacial Till
The influence of compaction water content on the structure has been well known forclayey soils, but has never been studied for granular materials. In this paper the structure of a nonplastictill and the effect of compaction moisture is investigated by means of water retention curvestudy, scanning electron microscopy and mercury intrusion porosimetry tests. The results show thatwhen compacted on...
متن کاملEstimation of Soil Infiltration in Agricultural and Pasture Lands using Artificial Neural Networks and Multiple Regressions
Common methods to determine the soil infiltration need extensive time and are expensive. However, the existence of non-linear behaviors in soil infiltration makes it difficult to be modeled. With regards to the difficulties of direct measurement of soil infiltration, the use of indirect methods toestimate this parameter has received attention in recent years. Despite the existence of various th...
