RAINS PROVIDE SOME RELIEF

Rains across much of the state provided much needed moisture to most farmers. These rains also brought with them cooler temperatures with many areas reporting frost. Corn, soybean, and cotton harvests continued with most farmers continuing to post favorable yields. The added soil moisture from the recent rains have helped in the emergence of early planted winter wheat. Pasture conditions improved slightly after the rains, but frost kept pastures from making any big improvement and effectively put a stop to the grazing season in many areas. There were 5.2 days suitable for field work. Topsoil moisture was rated 20 percent very short, 24 percent short, 53 percent adequate, and 3 percent surplus. Subsoil moisture was rated 22 percent very short, 34 percent short, 43 percent adequate, and 1 percent surplus. You can read the entire report here: TN Crop Weather 10_21_2019.

Planning to get the most out of your crop next spring? Soil testing after post-harvest is a valuable step in accomplishing this goal. While soil testing is the only practical means to adequately evaluate the nutritional needs in a field to prescribe appropriate lime and fertilizer recommendations, the reliability of soil test results depends on the quality of the sample submitted to the soil testing laboratory. Poor sampling can result in inaccurate soil test results and produce unreliable lime and fertilizer recommendations. Some helpful soil sampling information:

•  Soil samples can be collected at any time, but some soil properties (soil pH, phosphorus (P), and potassium (K), for example) can vary depending on the time of sampling.
• While soil test results from University of Tennessee Soil, Plant, & Pest Center come back within 3 to 5 days, it is best to sample months ahead of planting to allow for planning and getting prices on lime or fertilizer.
• A good rule of thumb for soil sampling is to collect samples in a way that adequately represents the soil in that field. A well represented sample will consist of 10 – 20 core samples taken at the appropriate depth within a 5/10-acre grid.
• University of Tennessee Soil, Plant, & Pest Center as well as commercial soil testing laboratories in Tennessee recommend taking soil samples to a depth of 6 inches.
• The frequency of soil testing depends on cropping intensities, soil types, fertilization rate, tillage methods, and weather conditions; however, fields should be tested every two to three year to estimate the residual nutrient levels. For high-value cash crops (tobacco, vegetables, etc.) soils should be tested annually.
• Soil testing is also recommended any time a nutrient deficiency problem is suspected or at the beginning of different crop rotation system.
• Soil samples and a completed soil information sheet can be taken to your county Extension office or directly sent to University of Tennessee Soil, Plant, & Pest Center, Nashville.•

WIDELY SCATTERED SHOWERS BRING LITTLE RELIEF

Widely scattered showers occurred across the state last week, but these did little to relieve extremely dry conditions. Corn and soybean harvest continued with producers continuing to report favorable yields for both corn and early crop beans. In some areas, deteriorating pasture conditions forced livestock producers to start feeding hay, leading to concerns that they may run short of hay during the winter months. Availability of water for livestock was also a concern, with some farmers having to haul in water for their herds. There were 6.1 days suitable for field work. Topsoil moisture was rated 35 percent very short, 43 percent short, and 22 percent adequate. Subsoil moisture was rated 28 percent very short, 53 percent short, and 19 percent adequate. Hay & Roughage Supplies rated 1percent very short, 13 percent short, 72 percent adequate, and 14 percent surplus. You can read the entire report here: TN Crop Weather 09_30_2019.
