The Soil Drainage and Productivity Indexes provide information on the Drainage Index (DI) and Productivity Index (PI) of all soils that are classified within the US system of Soil Taxonomy. These data aid in the identification of areas at risk to various forest insects and diseases because of their ability to identify regions of potential tree stress.

Detection surveys are the primary method of collecting Geospatial data on the health of treed areas affected by insects and disease and stored in a National Insect and Disease Survey (IDS) database. This process involves conducting annual aerial and ground surveys using the following systems:
With the growing need to conduct complex spatial analysis and manage large datasets, the GIS and Spatial Analysis program has begun to develop applications to aid in data management and analysis. Examples of applications developed by FHAAST include:
FHAAST provides support for both tactical and strategic forest health risk assessments. In addition, this program coordinates, in collaboration with the USDA Forest Service Forest Health Monitoring program (FHM), the development of a National Insect and Disease Risk Map (NIDRM) and database.
The Individual Tree Species Parameter Maps (ITSP) map basal area and stand density index for each individual tree species. The parameter products are based on 30-meter Landsat satellite data, climate, terrain, and soil predictor layers and ground samples from the USFS Forest Inventory and Analysis plot data.
The maps are an integration of various sources, reviewed by regional authorities. They are intended to display the biological extent of major damage agents, or the range over which they have been a managerial concern.
The Soil Drainage and Productivity Indexes provide information on the Drainage Index (DI) and Productivity Index (PI) of all soils that are classified within the US system of Soil Taxonomy. These data aid in the identification of areas at risk to various forest insects and diseases because of their ability to identify regions of potential tree stress.
The SPB Prevention and Restoration Program, along with local and regional resource managers, use the maps in planning activities and also to prioritize where prevention and restoration treatments should occur on the landscape to get the most cost-effective treatments.

Planting the same crop year after year on the same piece of land strains soil resources.
Different crops demand more soil nutrients while adding other nutrients. For example, legumes use more phosphorus and potassium than nitrogen. Soybean monoculture will result in excess nitrogen in the soil and less of other nutrients. Such imbalances mess with soil health.
Various bacteria and microorganisms replenish the soil and keep it fertile. Different microbes mean many kinds of nutrients and soil health services. Research has established that plant diversity influences soil health and the type of microbial community in an area2. With monocropping, the variety of microbes significantly decreases.
Nutrient pollution
Since monoculture depletes soil nutrients, farmers must maximize production by using chemical fertilizers. However, there are severe environmental costs associated with using artificial fertilizers. Chemicals from fertilizers enter rivers, lakes, streams, and reservoirs through rainfall runoff or erosion, and they can also seep into groundwater.
Oversaturation of soil nutrients in aquatic habitats can cause harmful algae blooms, depleting the water's oxygen. Swimming in or accidentally swallowing water contaminated by such algae can cause serious health issues. Soil nitrate can also find its way into our drinking water. Water with high enough nitrates can be fatal to infants.
Excess fertilizer use also contributes to climate change. Nitrogen-based chemical fertilizers produce nitrogen oxide (N2O), a greenhouse gas with 265 times more warming power than carbon dioxide3.
The soil brown (Maniola jurtina) is a butterfly found in the Palearctic region. Also south are Europe, Russia east to the Urals, Asia Minor, Iraq, Iran, North Africa, and the Canary Islands. They feed on larval grass.
When trying to figure out how to use Epsom salt for plants, always remember that testing and retesting is key. So, before adding Epsom salt to your garden, it’s a good idea to test your soil’s magnesium levels. If your soil already contains adequate magnesium, adding more could be unnecessary and potentially harmful.
