Short comparison of ZM-Grow solution and chelated fertilisers

This white paper describes the difference between foliar sulphate fertiliser ZM-Grow and foliar chelated fertilisers.

Sulphate and chelate based fertilisers are commonly used in foliar fertilisation. Both are completely water soluble, and (...)

Short comparison of ZM-Grow solution and carbonate/oxide suspensions

This white paper describes the differences between foliar sulphate fertiliser ZM-Grow and foliar carbonate and oxide fertilisers.
ZM-Grow is a 100% sulphate solution, where the micronutrients are completely dissolved into water as sulphates (ZnSO4, MnSO4). Foliar fertilisers (...)

Soil Conditions And Micronutrients

Macronutrient fertilisers (NPK-fertilisers) are commonly given to plants as soil-added granules. The granules slowly break down in the soil, and the nutrients are absorbed through the plant’s roots.

With micronutrients, such as zinc and manganese, application through the soil can be affected by various soil conditions.

ZM-Grow User Instructions

1. Shake the container well: after long storage times, there might be some sedimentation which dissolves with mixing in warm conditions.

2. First, do a bucket-sized mixing experiment combining ZM-Grow™, water, (...)

Using Alkaline Batteries As Raw Material For Fertilisers

Alkaline batteries contain high amounts of zinc and manganese, around 50% of their weight. Both micronutrients are important for plant nutrition, making batteries a viable and widely available source of micronutrients.
