CaTs® is a clear liquid fertilizer containing calcium and sulfur that reduces the harmful effects of salt, such as sodium, in the soil, and it can work as a soil amendment.
N-Sure® (28-0-0) is a clear, liquid nitrogen fertilizer containing the patented slow-release nitrogen (SRN) compound Triazone™, which enhances nitrogen absorption, translocation and remobilization.
Year: 2015
Cooperation with: Farmer Anthony Forgerit/Arvalis
Type of application: fertigation
Parameters measured: yield, nicotine, calcium, potassium, sulfur, dry matter
Goal: measure use of CaTs®, KTS®, N-Sure® to take out of a growing heterogeneity problem
METHODOLOGY
Applications of CaTs®, KTS®, N-Sure® have been done to solve several issue:
- CaTs® to improve homogeneity and solve crusting soil trouble.
- KTS® to improve tobacco growing and good quality on leaves quality.
- N-Sure® to support extra development with small nitrogen input.

CONCLUSION
This small schedule of N-Sure®, CaTs®, KTS® during two months of growing have very good results on tobacco growing. Heterogeneity disappear and fertilizer apply affect the yield.
Our fertilizer improve the yield of 5.6% on dry matter. Incomes uptake of 588€/ha with input increase of 99.46€/ha, the farmer margin improve of 488€ /ha!
CaTs® and KTS® added give a better control on nicotine rate which is a very important topic on tobacco leaves. Too high level of nicotine could be a lower sale price for the farmer. Potassium and calcium are very important in tobacco growing, our fertilizer show a very good efficiency to work through a growing issue. Leaves analysis indicate a better assimilation of calcium and potassium.
