Soil health is the foundation of productive farming practices. Fertile soil provides essential nutrients to plants. Important physical characteristics of soil-like structures and aggregation allow water and air to infiltrate, roots to explore, and biota to thrive. Diverse and active biological communities help soil resist physical degradation ...

Solar panels' effect on soil moisture can help increase energy independence and reduce water consumption while boosting crop yields. Another area to examine is the redirection of runoff from panel surfaces. When channeled properly, this rainwater can be used for irrigation, further reducing demands on your farm.

One of the biggest problems with construction is sediment — fine silt that comes from loose soil — that pollutes waterways and damages aquatic habitats. Sediment pollution can also affect drinkable water sources and fisheries, and plays a role in potential flooding issues. Most often, sediment is not the only thing that ends up in the water.

Agricultural land use planning is based on the capacity of the soil to support different types of crops and is a prerequisite for better use of cultivated land. Land Suitability Analysis (LSA) is used to measure the level of suitability of growing a specific crop in the area and can also be used to evaluate future scenarios as a means for sustainable …

Tillage can both help and harm soil quality, so it is important to consider carefully how and when you till. On one hand, proper tillage breaks up compaction, aerates the soil, and incorporates raw organic matter. However, too much or improper tillage reduces soil organic matter content and can destroy soil aggregates.
