Focus on Spring Fert Spread
Southern Humates continues to invest heavily in independent scientific field trials. 1st Trial 2014 – 2019 Increase in Pasture Production – This comprehensive five-year study has proven the addition of 20% humates to urea increases pasture production. Humates improve nutrient efficiency, enhance root development, and promote microbial activity, leading to...
Five Things to Know About Humic Acid
Most of us know about humic substances, and how they increase the ability of the soil to hold water and build organic matter. When we discussed humic acids at the Healthy Soil Summit, the audience wanted to know more details. Here are five other key things to know about humic...
Humates a good regen farming input
Regenerative agriculture has started to build in momentum as a movement within New Zealand pastoral farming, with field days and seminars held around New Zealand drawing dozens of farmers to them.
Study reveals humates boost nitrogen benefit
A long term field trial in Southland has found using humates in combination with urea fertiliser will lift pasture production by 10-15% above urea use alone.
Bioactive carbon improves nitrogen fertiliser efficiency and ecological sustainability
Agriculture’s most pressing challenge is raising global food production while minimising environmental degradation. Nutrient deficiencies, principally nitrogen (N), limit production requiring future increases in fertiliser use and risk to proximal non-agricultural ecosystems. We investigated combining humate with urea, globally the most widely used N-suppling fertiliser, in a four-year field study....
