Defense-Mag is intended as a soil application for rectifying areas with Mg deficiency. Extreme deficiencies should be rectified with multiple applications over a longer period. Regular soil analyses are recommended for monitoring the Mg level in the soil.
The soluble material is added to the containers with lukewarm water and added to the sprayer. Switch on agitator! The application is with 600-800l water per hectare and should then be watered in. For a strong deficiency, 12.8 kg/ha of Defense-Mag should be applied. Water slightly after application. Repeat application after 4-6 weeks if required. Defense-Mag is not recommended for use with high Mg content in rain water or if the Mg content in the soil is sufficient.
