Effects of different tillage management on the growth and yield maize were studied from early June to September 2017. The experiment was set up with three treatments: traditional shallow moldboard plow straw removal (MT), sub-soiling/ /sub-soiling rotation mulch (ST) no-till/sub-soiling/no-till retention (NT). soil compaction layers, plant height, chlorophyll content, above-ground biomass deter...

Traditional tillage represents a serious threat to the stability of soil ecosystems. Understanding response mechanisms microbial community assembly different practices is major topic ecological research. Here, we investigated bacterial structures and in bulk rhizosphere soils soybeans grown under traditional (moldboard plow, MP) two conservation practices, namely, no-tillage (NT) ridge (RT), us...

At present, the role of agricultural practices on dynamic GHGs is being investigated worldwide. In this study, effects soil tillage (conventional vs. conservation techniques) and fertilization sources (inorganic organic) CO2 emissions in durum wheat (Triticum Desf.)–potato (Solanum tuberosum L.) rotation Mediterranean area were evaluated. This study aimed to understand changes carbon content un...

Stratification of nutrient availability, especially of P, that develops with continuous no-till (NT) can affect runoff nutrient concentration and possibly nutrient uptake. The effects of composted manure application and one-time tillage of NT on the distribution of soil chemical properties, root colonization by arbuscular mycorrhizae (AM), and plant P uptake were determined. Research was conduc...

The use of 1,2-dibromo-3-chloropropane (DBCP) and e thy lene d ib romide (EDB) as soil fumigants to control nematodes has been banned. Other nematicides are more expensive and often less effective than DBCP and EDB and may experience a similar fate. A renewed interest in biological control o f nematodes will surely follow. Among root-knot nematode-resistant crops that may be used in rotation wi...

Plant-soil relations may explain why low-external input (LEI) diversified cropping systems are more efficient than their conventional counterparts. This work sought to identify links between management practices, soil quality changes, and root responses in a long-term cropping systems experiment in Iowa where grain yields of 3-year and 4-year LEI rotations have matched or exceeded yield achieve...

Papers published in Hydrology and Earth System Sciences Discussions are under open-access review for the journal Hydrology and Earth System Sciences Abstract The traditional tillage implement, the Maresha plow, and the tillage systems that require repeated and cross plowing have caused poor rainfall partitioning, land degradation and hence low water productivity in Ethiopia. Conservation tillag...
