Two rows of corn at V5 leaf growth stage looking down from above. Between the corn rows there are 3 separate cotton strips placed on the soil surface just before burial in a 2-inch-deep trench. The cotton strips are numbered for their identification after recovery at three different dates.

Cotton Strip Soil Test: Rapid Assessment of Soil Microbial Activity in the Field

Soil has always been considered as a living system due to its biological components: fungi, bacteria and plant roots. Under several ongoing research projects, we started researching how we can use ‘cotton strip assay’ to compare different cover crop mixes to optimize field soil activity and build up better soil health.

Fall Tillage: Please Don’t Think About It

Conducting fall tillage results in lost topsoil, soil nutrients, and soil moisture. This ultimately leads to reduced soil productivity and profitability. An easy way to conserve topsoil and water resources is to skip fall tillage.

Monitoring and Correcting Magnesium Deficiency in High Tunnels

This point in the growing season is a good time to monitor and correct for magnesium deficiency in high tunnel crops, especially on tomatoes. Deficiency symptoms normally appear mid-season on plants with heavy fruit loads.

Choosing Whether to Preharvest Broadcast Vs. Post-Harvest Drill Cover Crops

Cover crops are frequently planted following the harvest of the grain commodity crops. A decision for producers to make is to whether to preharvest broadcast or postharvest drill the cover crop.
