Nanoclay for Controlled-Release Fertiliser: Extending Nutrient Availability Without Polymer Coatings

Mon, 25 May 2026 00:00:00 +0000

Of every kilogram of nitrogen fertiliser applied to agricultural soil worldwide, a substantial fraction never reaches a plant. It leaches through the soil profile into groundwater, volatilises as ammonia or nitrous oxide into the atmosphere, or runs off in irrigation water or rainfall events. The estimates vary by crop, soil, and application method, but losses of 30–50% are typical for conventional urea under typical application conditions.

This is simultaneously an economic problem (fertiliser is expensive, and losing half of it is a direct cost to growers), an environmental problem (nitrate leaching and nitrous oxide emissions are significant contributors to water pollution and greenhouse gas loading), and an agronomic problem (uneven temporal availability of nutrients creates periods of excess and deficit that reduce yield).

Nanoclay for Soil Water Retention: How It Works and Where It Wins

Thu, 21 May 2026 00:00:00 +0000

Water is the primary constraint on agricultural productivity in most of the world’s dryland farming regions. Of all the approaches to improving water use efficiency at the soil level — mulching, deficit irrigation, crop variety selection, soil organic matter accumulation — nanoclay amendment is one of the least understood and, in the right soil types, one of the most effective.

This article explains how nanoclay retains water in soil, which soil types benefit most, and how to think about the technology alongside the more familiar alternatives.

Nanoclay-Biochar Combinations: A New Frontier in Soil Amendment Science

Mon, 04 May 2026 00:00:00 +0000

Biochar and nanoclay have each attracted substantial attention as individual soil amendments. Biochar for its carbon sequestration, long-term soil organic matter contribution, and microbial habitat. Nanoclay for its water retention, nutrient slow-release, and structure improvement in sandy soils. The natural question — what happens when you combine them — turns out to have an interesting answer.

The combination is not merely additive. Nanoclay and biochar interact physically and chemically in ways that modify each other’s properties, sometimes synergistically improving performance that either component provides alone.
