Effect of Cover Crops on the Critical Period for Weed Control in Soybean and Corn
(2024-04-22)
Soybean is the world’s most widely grown leguminous crop and is an important source of
oil and protein for food and feed in addition to other industrial uses. However, herbicide-resistant
and troublesome weed control ...
Effect of Phosphorus Fertilizer Placement on Corn and Soybean Yield in Phosphorus Stratified Soils of Alabama
(2023-06-27)
Alabama has highly weathered soils making them prone to erosion during intense precipitation events. Adopting conservation tillage practices is encouraged to minimize soil erosion and improve soil health. Currently, Alabama ...
Effect of Plant Growth Regulators and Biostimulants with and Without Foliar Nutrition on Reduced-Lignin Alfalfa (HarvXtra®)
(2021-08-05)
Known as the “Queen of Forages,” alfalfa (Medicago sativa L.) is regarded for its high protein content and palatability, making it the preferred feedstuff for high-producing dairy cows. The introduction in (2005) of ...
Effect of Real and Simulated Traffic on Coated Fertilizer Prill Integrity and Nitrogen Release
(2017-01-10)
The amount of nitrogen (N) from air and soil is not sufficient to produce high quality turfgrass, and thus N fertilizers are often applied. Urea is the most widely-produced and commonly-traded N fertilizer, containing 46% ...
Effects of Cover Crop Mixtures on Biological Indicators of Soil Health under Conservation Systems
(2019-02-04)
Soil management practices affect the health and productivity of agroecosystems. Cover crops, which are grown between periods of cash crop production, play a critical role in building healthy soil. The most obvious benefit ...
Effects of Drought Stress on Floral Hemp (Cannabis sativa L.) Agricultural Systems
(2023-04-18)
Hemp (Cannabis sativa L.) is a crop of renewed interest in modern agriculture. However, for it to be considered hemp and not marijuana, it must have a total THC concentration of no greater than 0.3%. Drought is a common ...
The Effects of Polyethylene and Cereal Rye Mulch, Tillage, and Herbicides on Tomato and Watermelon Yield and Weed Control
(2017-01-11)
Cereal rye, polyethylene mulching, and tillage all have an impact on the yield and growth of weeds. Herbicides have been used to control weed growth for decades. Using these in conjunction can possibly demonstrate ways to ...
The Effects of Soil Surface Temperature and Relative Humidity on 2, 4-D Volatilization
(2018-04-27)
Monolayer water content and specific surface area are two of the most significant
characteristics of soil. The monolayer water content (m0) and specific surface area measurements
were made by both Brunauer Emmett Teller ...
Efficacy and Antagonism of Pinoxaden Alone and in Combination with Other Pesticides for Annual Grass Control
(2019-11-14)
Pinoxaden is an acetyl coenzyme A carboxylase (ACCase) inhibiting herbicide in the phenylpyrazoline chemical family. Recently, pinoxaden was labelled for turfgrass use with a limited number of labelled susceptible weeds. ...
Evaluating Potential Agricultural Use of Industrial Byproducts
