Land use changes in the Everglades Agricultural Area (EAA) of south Florida may alter microbial activity and organic matter decomposition and ultimately influence the fate of P in soil. The objectives of this study were to determine effects of long-term cultivation and fertilization on microbial activity and P dynamics for contrasting land uses in the EAA. Soils (0-15 cm) under pasture for 100 ...

The effects of soil management systems on root-knot nematode (Meloidogyne incognita) eggs and gall incidence on tomato (Lycopersicon esculentum) and cucumber (Cucumis sativus) following tomato were evaluated. Soil was collected from a replicated field experiment in which six management systems were being assessed for vegetable production. Soil management systems were conventional production, or...

The objective of this study was to determine the effects of stage of lactation (SOL) and time of year on plasmin-derived proteolytic activity in the milk of pasture-fed dairy cows in New Zealand. Four herds of 20 Friesian cows were used, one herd calving in each of January, April, July and October. Cows grazed ryegrass/white clover pasture only, except during June (winter) when all cows receive...

Changes of land use/land cover have a significant impact on runoff by altering the surface evaporation, soil moisture conditions and the amount of trapped ground cover, which directly impact the sustainable development of the watershed ecology. In this paper, based on remote sensing images, we simulate runoff of land-use changes of different slopes using GIS technology and SWAT model in Erhai w...

We studied nitrous oxide (N2O) fluxes and soil nitrogen (N) cycling following forest conversion to pasture in the central Amazon near Santarém, Pará, Brazil. Two undisturbed forest sites and 27 pasture sites of 0.5 to 60 years were sampled once each during wet and dry seasons. In addition to soil-atmosphere fluxes of N2O we measured 27 soil chemical, soil microbiological and soil physical varia...

Nomadic pastoralism has thrived in Asia’s rangelands for several millennia by tracking seasonal changes in forage productivity and coping with a harsh climate. This pastoralist lifestyle, however, has come under intense transformations in recent decades due to socio-political and land use changes. One example is of the high-altitude trans-Himalayan rangelands of the Jammu and Kashmir State in n...

Recent research on grassland problems has made prominent the importance of strain in pasture species, The strains of grasses and clovers sown determine to a very large extent for what purpose the pasture is most suited, what its carrying capacity will be, and also the extent of its useful life, i',iost of the pasture species when studied show some strain difference, and so it is the object of t...

This article investigates the behavioral drivers of pasture creation and associated implications for deforestation in a 22,000 km2 agricultural frontier spanning the base of Mexico‘s southern Yucatán. After developing a theoretical model that highlights the role of social networks and information spillovers with respect to the decision to begin cattle ranching, we use household data to estimate...

Investigation of Listeria monocytogenes transmission from environmental sources associated with pasture-raised chickens to poultry products is needed to determine ways to prevent potential foodborne illness. Here, we report the complete genome sequence of Listeria monocytogenes MR310, one of the isolates from a pastured-flock poultry management system.

Steep, uncultivable hill country below 1,000 m comprises about 40% of New Zealand's land surface area. Hill farmers require options to increase the resilience their farms climatic and economic extremes while addressing soil conservation water quality issues. We profile discuss two that can assist in transforming country. The first a simple approach grazing management pastures pasture second foc...
