Effects of biowaste compost amendment on soil microbial biomass and specific carbon turnover in agricultural soils
The importance of biowaste compost as organic fertilisers has become more emergent in the last years due to the increased production of compost produced from biowaste. The utilisation of organic fertilisers in agriculture improves the physical, chemical and microbial properties of soils (Allievi et al., 1993; Senesi, 1989). Amendment of compost affects several soil properties positively like e.g. ...

Cadmium toxicity in plants
Cadmium is a heavy, non-biodegradable metal that is toxic to plants, people, and animals. With increasing pollution and emission of cadmium, its levels in agricultural soils are increasing. The risk to humans is high due to consumption of cadmium-contaminated food. Modern applications of gas analysis and laser measurements are speeding up research in addressing the problem of cadmium stress. ...

Regional Assessment of Nutrient and Pesticide Leaching in the Vegetable Production Area of Rattaphum Catchment, Thailand
Regional groundwater vulnerability maps to indicate the impact of leaching of chemicals under different management scenarios were prepared for the Rattaphum Catchment using several leaching models and GIS techniques. The Attenuation Factor (AF) model was used to simulate the leaching potential of several pesticides for selected soils in the catchment under different rates of recharge from ...

Agronomically Speaking: Fall Fertility? From Soil Test to Prescriptions
Farmers understand that soil fertility is a key component of growing healthy and high yielding crops. While there is much debate on how we accomplish soil fertility and health, there are some general items that are helpful to remember. However, because it was an extremely wet year for many across the country it is even more important to soil test this year. Some of the nutrients ...

Organic Matter: Key for sustainable agriculture
The growth in human population has had an important impact on soil and the services and resources it can provide. The consequences of human activities on soil resources resulted in the loss of biodiversity, accelerated erosion, desertification, compaction, nutrient depletion, and loss of soil organic matter (SOM), which is primarily made up of carbon (58%). Considerable losses of soil carbon ...

What is conservation agriculture?
With a lot of noise currently surrounding sustainability in British agriculture, there are many conflicting viewpoints on the best approach farmers should take to care for their environment. In this blog, we discuss conservation agriculture, and how by looking after your soil, you’re looking after your bottom line. We explore how it can benefit farmers to increase yields and lower crop ...

Soil Water Sensors for Agriculture – Theory and Issues
Soil water sensors have been used for irrigation and water management in agriculture for many years, but with limited success in many cases. Nonetheless, the use of soil water sensors in increasing as water scarcity increases and, conversely, problems associated with over irrigation also increase. Common problems with soil water sensing included sensor failure, problems with wiring, lack of or ...

Soil tensiometer
What is a soil tensimeter? Soil tensimeter uses the principle of negative pressure to measure soil moisture and studies soil moisture movement from the perspective of energy. Transparent PVC pipe can clearly see the amount of water, low-end with high-quality clay head, fast sealing, accurate measurement. Soil tensiometer is a practical method to measure soil condition by using a negative pressure ...

Model forecasts long-term impacts of forest land-use decisions
The drive to develop crops for use as biofuel, continues to raise questions about additional uses of forest land. A cutting edge computer model developed at North Carolina State University offers detailed insight to predict the environmental impact – along with understanding forest ecosystem response to global climate change. “We think the model will help policy makers and forest ...
