Agronomical target

  • Biostimulation
  • NUE
  • Organic farming

Van Iperen Plants for Plants 4-Terra is part of the new generation of plant-based Biostimulants developed for a more sustainable agriculture.

4-Terra has a proven dual action on enhancing Nutrient Use Efficiency (NUE) of the crop both on soil microflora as well as on the plant itself, making it a unique solution combining soil and plant action.

4-Terra has been developed for all fertigated crops in both comfort and stress conditions. Applied in fertigation during the early stages of the crop cycle, 4-Terra will improve the crop establishment ensuring a better nutrient uptake throughout the crop cycle, resulting in higher yields and crop quality.

  • Fully controlled process from plant material to final product
  • Enhancing NUE, ensuring higher yield and crop quality
  • Improving Phosphate assimilation by combining plant and soil action
  • Suitable for organic farming in compliance with European Regulation (EU) 2018/848
  • Safe for users, consumer and for the environment
  • Developed for fertigation and soil application

Fertigation

Crop Application date Max L/ha/season
Fruit trees and Vineyards
• Split over at least 3 to 4 times during fertigation program from early start until fruit set stage 16-18
Vegetables
• Split over at least 3 to 4 times during fertigation program from start until early production phase 16-18

Mode of action

Genomic and metabolomic methods have identified a clear mode of action for 4-Terra. 4-Terra improves Phosphate assimilation thanks to an up-regulation of PHT2;1 gene a chloroplastic Phosphate transporter. Furthermore, we measured a significant increase of microbial population allowing P solubilization in the soil (microbiome effect).

The mentioned indicated dosages and application stages are given as a guideline. Exact dosages, concentration and application stage are subject to local conditions, use of other fertilizers and can only be given after an objective diagnosis.
