Tillage operation and fertilizer type play important roles in soil properties as far as soil microbial condition is concerned. Information regarding the simultaneous evaluation of the effect of long-term tillage and fertilization on the soil microbial traits of soybean farms is not available. Accordingly, it was hypothesized that, the microbial biomass and enzyme activity, more often than not, ...

In this study, a fixed-site field experiment was conducted to study the influence of different combinations of tillage and straw incorporation management on carbon storage in different-sized soil aggregates and on crop yield after three years of rice-wheat rotation. Compared to conventional tillage, the percentages of >2 mm macroaggregates and water-stable macroaggregates in rice-wheat double-c...

To determine the relationship between changes in soil physical properties due to tillage and growth of loblolly pine (Pinus taeda L.) seedlings, we measured soil moisture and penetration resistance for a range of tillage treatments on two Upper Coastal Plain sites in Georgia and correlated these measurements to the growth of individual seedlings. The five tillage treatments were: no-till (NT), ...

Conservative agriculture is considered as an alternative to tackle the need for increased agricultural production based on sustainable agriculture activities with the aim of increasing production and product stability along with preserving the environment. Tillage is one of the most important factors affecting soil structure. Selection of appropriate tillage systems varies according to the cond...

conservation tillage, a fast growing practice in iran, is considered as a means to achieve sustainability in agricultural systems. this study was carried out to determine the effect of tillage systems (no-tillage, minimum tillage and conventional tillage ) on yield and yield components of three irrigated wheat varieties. the field experiment was conducted at the experimental station of the univ...

BACKGROUND A three-year field experiment was conducted to examine the responses of corn yield and soil nitrous oxide (N2O) emission to various management practices in middle Tennessee. METHODOLOGY/PRINCIPAL FINDINGS The management practices include no-tillage + regular applications of urea ammonium nitrate (NT-URAN); no-tillage + regular applications of URAN + denitrification inhibitor (NT-in...

Wilhelm, W.W., Hinze, M.R. and Gardner, C.O., 1991. Maize hybrid response to tillage under irrigated and dryland conditions. Field Crops Res., 26: 57-66. The popularity of reduced-tillage cropping systems has emphasized the need to determine if maize (Zea mays L.) developed under conventional tillage systems (moldboard plow, disk, and harrow) is readily adaptable to conservation production syst...

NT will reduce soybean grain yields and economic returns, particularly during the first few years of adoption. Farmers have been encouraged to adopt no-tillage (NT) because Soybean grain yield response to NT systems depends of its positive environmental effects compared with other conservation tillage systems. Nevertheless, poor crop performance under NT manmainly upon soil drainage and previou...

Cotton (Gossypium hirsutum L.) yield and quality responses to irrigation have not been described for conservation management systems that growers are rapidly adopting. We conducted a field experiment from 2001–2003 in the Tennessee Valley near Belle Mina, AL on a Decatur silt loam (fine, kaolinitic, thermic Rhodic Paleudults) to examine how irrigation regimes and tillage systems affect ginning ...
