True or False: Herbicides leach more readily through coarse, sandy soil low in organic matter.

The statement is true because coarse, sandy soils typically have larger particle sizes and greater porosity compared to finer soils. This physical characteristic allows water, along with dissolved herbicides, to move more freely through the soil profile. In addition, sandy soils usually have lower organic matter content, which plays a crucial role in herbicide retention. Organic matter can bind with some herbicides, effectively reducing their mobility. In soils low in organic matter, the potential for herbicides to leach is increased, especially during precipitation events that promote the movement of water and soluble substances through the soil.

This understanding of soil types and their effects on herbicide behaviors is critical for effective herbicide application and management strategies in agriculture and land management practices.
