Marasperse AG increases tomato crop yield

Field demonstrations in a soil application for tomato crops show the benefits of Marasperse® AG under alkaline soil conditions with high demand for iron micronutrient. Marasperse AG increased tomato crop yield over an EDTA chelating agent.

This work was conducted by Syntech Research in Andalusia, Spain. Under greenhouse fertigation conditions, the tomato crop received weekly applications of Fe, Zn, Mn, Cu, Mo and B containing fertilizers. The comparative study between fertilizers with Marasperse AG and a formulation with a synthetic chelate (EDTA) evaluated iron foliar level and the agricultural yield.

Key takeaways:

  • Tomato crop yield increase over EDTA
  • Micronutrient uptake similar to synthetic chelates
  • Bio-based and organic certified
