During the last couple of weeks in December and into early 2021, eastern Ohio saw warmer-than-usual temperatures and a lot of rain. What does this mean for our pastures and hay fields?
With rain comes the mud, and with mud often comes compaction. Compaction in forage crops often occurs withing the top 3-4 inches of soil, but it can also appear at deeper levels, forming ‘hard pans’ that restrict the movement of water.
Compacted soils mean reduced pore space to house water and air – two important components of healthy soils. Nearly half of soils should consist of pore space, whether macro- or micro-pores to allow roots to develop deeper and water to better infiltrate downwards. Compaction can ultimately lead to increased drought and disease susceptibility of plants, even when it appears there is standing water in a field.
Another key component of healthy soils is the soil biology – microorganisms, earthworms (not the jumping worm kind), and fungi among others help to break down organic materials that improve soil structure and add pore space. When soils are compacted, these biological processes stall, leading to a Continue reading What to Do with Muddy, Compacted Pastures?
