To develop a fertilizer plan to maximize hay yields, your forage can never be hungry for nitrogen or other essential nutrients like phosphorus or potassium. There is still a need to collect data in the water dissolving time, foliar absorption, and application rates that are economically sustainable. Grasses cannot tell the difference between nitrogen supplied by the granular and liquid fertilizers, but the fertilizer application, effi-cacy, and uptake can impact biomass production and nutritive value. Although some of the liquid fertilizer had lower cost per pound of seasonal dry matter produced, their percent yield increase compared to the control were lower than the granular fertilizers across both application rates. The granular fertilizers (urea and urea ammonium sulfate) had greater crude protein concentrations than the rest of the liquid fertilizers across the recommended or adjusted application rates. However, their increase in biomass compared to the control were lower than the granular fertilizers or UAN.

When the liquid fertilizers were applied at the rate of 50 units of N per cut of hay, there were not significant different from the granular fertilizers. 2), nutritive value, and cost per pound of biomass production (Table 1). This preliminary data indicates that liquid fertilizer applications into your in-season nitrogen program have not proven beneficial at the manufacturer recommended rate in terms of biomass production (Fig. Hay was harvested in approximately a 30-day interval and there were three harvests. All treatments were adjusted for phosphorus Volume 15, Issue 12 December 2022 Liquid Fertilizers and Their Role in Hay Production Rocky Lemus Extension Forage Specialist Visit us at: Forage News December 2022 and potassium based on soil test recommendations. The other three fertilizers were applied at the manufacturer’s recommendation of one gallon of product per acre or adjusted to meet the recommended rate of 50 units of nitrogen per acre per cut of hay.

The UAN fertilizer was applied at 50 units of nitrogen per acre per cut of hay only.

The liquid fertilizers included urea ammonium nitrate solution (UAN, 32-0-0), Agritech Plus (AGP, 10-20-0), Pasture Booster Pro (PBP, 30-0 -0), and Royal Grow (RG, 30-0- 0). Granular fertilizers were applied at rate of 50 units of N per acre per cut of hay. The granular fertilizers were urea (U, 46-0-0) and urea ammonium sulfate (UAS, 33-0-0). The treatments included a control (C), two granular fertilizers, and seven liquid fertilizers. The replicated study consisted of ten treatments. Another claim is these fertilizers can increase protein and energy concentration, improve digestibility, and optimize growth, increase forage biomass and utilization while improving animal performance.Ī preliminary study was conducted at Mississippi State on ‘Tifton 9’ bahiagrass.

Most products indicate that liquid fertilizers are comparable to granular fertilizers while providing advantages such as greater accuracy of application, improved nitrogen use efficiency, and reduced losses with effective cost. There are multiple liquid fertilizer products flooding the market with production claims without research data that can validate their efficacy, production, improvement in nutritive value, and economic return. The increase in nitrogen (N) fertilizer prices has forage and livestock producers searching for other alternative sources that could allow sustainable forage production and profitability (Fig.
