This factsheet tells homeowners how to recognize and prevent problems with home septic systems. How septic systems work, where septic systems can be used, and maintenance on septic systems are covered.
This factsheet describes the effect of fertilizer nitrogen on water quality and the environment. It provides guidelines for managing soil fertility on farms to preserve water quality.
This factsheet for farmers describes ways to control the harmful effects of excess nutrients while maintaining healthy, productive farm crops. Steps covered include testing your soil and following the soil testing recommendations, setting realistic yield goals, choosing the most suitable nitrogen sources, applying nitrogen correctly, using manure as a nutrient source, controlling erosion, managing water flow and fencing animals away from water flow.
This publication discusses best practices management to prevent agricultural activities from contaminating groundwater. It covers the role of soil on the quality of groundwater, soil characteristics, characteristics of potential pollutants and management practices such as nitrogen and pesticide management.
In our drive to meet the food and fiber needs of ever-increasing populations, we are taxing the resilience of the planet’s natural resources. This fevered quest to pursue ever-increasing crop yields has had devastating impacts: widespread soil erosion, atmospheric pollution, over- grazed forage areas, over-cultivated fields, salinated water supplies, cleared land that is unsuitable for crops, and desertification —the loss of agricultural land to desert. The serious degradation of our soil resources has motivated some researchers and farmers to investigate management systems that are less input-intensive and generally more sustainable.
