This is a mixture of cattle manure, poultry manure, food waist and plant compositions. Mainly to improve the carbon nitrogen ratio and EC electrical conductivity in the soils. This will help improve the physical structure of soil and will improve water retention, soil porosity and will increase nutrient availability to plants. Also prevents nutrient leaching or washing away. The Improved soil structure will optimize the use of nutrients available naturally from air, water and organically available or externally provided.



Nutri Keta Compost mixture granulated to improve keeping quality and handling capability to apply to fields.



Compost mixture is enriched with approved organic minerals such as rock phosphates, potassium chlorides and magnesium sources available naturally in Sri Lanka based on meeting the nutritional requirements of different crops.

Agri Silica


Agrisilica soil conditioner is composed of a unique natural form of silicon, sourced from the world’s largest deposit of amorphous silica located in Australia. The high concentration of soluble silicon (26% W/W), which is readily converted in to plant available silicon (PAS), makes Agrisilica soil conditioner unique.
To optimize crop performance, Agrisilica boosts soils by delivering a naturally derived silicon. Agrisilica’s unique structure interacts with soil moisture to form mono silicic acid (PAS). PAS’s 3 point plan to improve crop production and crop quality
1. Photosynthesis and crop health
2. Resilience against crop stress
3. Soil health and improved growing conditions



Compost mixture is enhanced with specific bacteria that are scientifically developed in laboratories to perform specific functions and activities that will enhance the nutritional value of these mixtures providing more nutrients at a faster rate to meet the demands of the crop. There are bacteria available naturally in Sri Lanka that will be extracted through state-of-the-art technologies.

Bio – F

Liquid Fertilizer

Bio-f is a bio-fertilizer produced by incorporating microorganisms that are beneficial for paddy cultivation. In addition to absorbing plant nutrients through the leaves, the microbial groups contained here colonize the plant roots and enhance the nutrient uptake of the crop. In addition, these microorganisms are involved in the production of substances that cause plant resistance

Bio – d

Liquid Fertilizer

Bio-D is a compost accelerator/decomposer. These are concentrated bacteria packages. When applied, they can jump start or bootstrap the decomposition process.

Bio – n

Liquid Fertilizer

Nitrogen is one of the most essential elements needed by plants for their growth and BIO – N high nitrogen and soil beneficial microorganism content makes it an ideal biofertilizer for tea.
