A single enzyme molecule can catalyse the same reaction thousands of times per second.

Proteins are the primary storage form of organic nitrogen in soil, compost, and organic fertilisers. Protease releases this nitrogen as amino acids and ultimately ammonium — the form that plant roots absorb. Faster protein breakdown means faster nitrogen availability. This is why growers report that organic fertilisers applied alongside malted barley produce visible results sooner than fertiliser alone.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"drf-mech\"\u003e\n\u003cspan class=\"drf-mech-num\"\u003e03\u003c\/span\u003e\n\u003ch4\u003ePhosphatase — phosphorus liberation\u003c\/h4\u003e\n\u003cp\u003eCatalyses the hydrolysis of organic phosphate compounds, releasing plant-available phosphate (PO₄³⁻).
