    🕔Apr 9, 2022
    The first planting of a planting date trial was sown at the Dean Lee Research Station on March 28, 2022. This research trial will also be planted at the Rice […]

    Louisiana Corn: Optimum Nitrogen Fertilizer Rate and Timing Mar 23, 2022

    🕔Mar 23, 2022
    Nitrogen (N) is the most yield limiting nutrient for corn production. The LSU AgCenter recommends 1 to 1.25 lbs of N per bushel of corn harvested i.e., a 200-bushel corn […]

    Louisiana: How Can We Cut Down Phosphorus, Potassium Fertilizer Rates in 2022? Mar 23, 2022

    🕔Mar 23, 2022
    Phosphorus (P) and potassium (K) fertilizer recommendations depend on Mehlich-3 soil-test P and K concentrations, respectively from soil sample taken from 0- to 6-inch depth in Louisiana. Fertilization is recommended […]

    Louisiana Soybeans: Consider Nitrogen Fixation When Planting Mar 22, 2022

    🕔Mar 22, 2022
    Soybean acreage has been projected to increase in 2022 in Louisiana as well as in several other states due, in part, to the high price of fertilizer. Since both corn […]

    Louisiana Corn: Should You Use N-stabilizers to Improve Nitrogen Use Efficiency? Feb 24, 2022

    🕔Feb 24, 2022
    Nitrogen fertilizers contribute to the major share of fertilizer costs, especially in corn production. At present, nitrogen use efficiency (NUE) of the applied N-fertilizers is often below 40% and has […]

    Louisiana Cotton: Diagnosing In-Season Potassium Deficiency Aug 20, 2021

    🕔Aug 20, 2021
    Potassium (K) is the second most critical nutrient after nitrogen (N) for cotton production. Potassium deficiency can cause significant lint yield reduction with reduced fiber quality. Cotton experiences K deficiency […]

    Louisiana Soybeans: Late-Season Nitrogen Application – Does It Work? Jul 19, 2021

    🕔Jul 19, 2021
    Nitrogen (N) is the most yield limiting nutrient for any row crop including soybean. Since soybean, like other legume crops, can fix atmospheric N symbiotically through Rhizobium bacteria (Bradyrhizobia japonicum), […]
