β-glucosidase is involved in the degradation of cellulose in soil and has the potential for monitoring biological soil quality. the objective of this study was to determine the effects of barley residue placement, burning, nitrogen fertilizer and tillage management on β-glucosidase enzyme after a period of 90 days. a field experiment was carried out based on a completely randomized design with ...

ern Tennessee (Stevens et al., 1992; Bradley, 1993; Triplett et al., 1996), conservation tillage practiced on silty clay Yield reductions from no-tillage cotton (Gossypium hirsutum L.) soils in northern Alabama resulted in 8 to 15% yield jeopardized adoption of conservation systems in the Tennessee Valley region of north Alabama in the early 1990s. We conducted a study from reductions compared ...

Soil organic C (SOC) and total N (TN) contents play a crucial role in sustaining agricultural production systems. Short-term ( 10-year) management effects on SOC and TN dynamics are often complex and variable. Three experiments were conducted to evaluate short-term tillage and cropping system effects on SOC and TN within the 0–30 cm soil depth across Iowa. The first experiment with no-tillage a...

Weeds are a serious problem of chickpea cultivation in rain-fed areas of Iran and economic feasibility of crop production is mostly challenged by the method of control. In this study, two types of weed control strategies which are common in the country, including hand removing and hand removing + mechanical application, were compared with application of general herbicide (Glyphosite) using a sp...

Context Shifting agricultural operations to more sustainable management practices is needed in the face of a changing climate. Aims In this study, short-term effects three tillage systems (no tillage, minimum and conventional tillage) on wide selection soil properties semi-arid agrosystem eastern Tunisia were assessed. Methods The studied included saturation percentage, bulk density, penetratio...

Intensive tillage, high fertiliser inputs, and plastic mulch on the soil surface are widely used by vegetable growers. A field investigation was carried out to quantify the impact of alternate land management and fertiliser practices designed to improve offsite water quality on the productivity of vegetable rotations within a sugarcane farming system in a coastal region of subtropical northeast...

Soybean is an important crop due to its multiple uses but also agronomic advantages. Regardless of the agrotechnical system practiced, in success crop, a very role represented by weed control. Soybeans are sensitive infestation with weeds both at early stages growing season until plants cover soil, maturity after leaves fall. A soil tillage applied, through effect on and control, influences soy...

Roots may respond to restrictive soil physical conditions and send signals to shoots to control plant growth. Soil mechanical resistance and aeration can be managed to improve the soil physical conditions for plant growth by using different tillage systems. The objective of this study was to quantify the influence of no-tillage and conventional-tillage systems on plant response to soil mechanic...

Anhydrous ammonia (AA) is a major fertilizer source in North America that can promote greater emissions of nitrous oxide (NO) than other nitrogen (N) fertilizers. Previous studies found that injection of AA at a shallow depth (0.1 m) decreased NO in a rainfed clay loam but increased NO in an irrigated loamy sand compared with the standard injection depth of 0.2 m. The objective of this study wa...
