According to a study co-led by The University of Queensland, a novel method of employing compost might enhance worldwide food output while also providing significant environmental advantages.

According to Professor Susanne Schmidt of the University of Queensland's School of Agriculture and Food Sciences, implementing a Precision Compost Strategy (PCS) in large-scale agriculture could improve crop yield, soil health, and divert biowaste away from landfill, where it emits harmful greenhouse gases.
Professor Schmidt said that PCS entails supplementing the proper sort of compost with nutrients to fit the demands of soils and crops rather than depending solely on mineral fertilizers, as per ScienceDaily.
Aerated and neutralized soils that had become compacted and acidic.
As a result, they can hold more water, promote root growth, and feed the organisms that keep soils and crops healthy.
According to Professor Schmidt, the soil is critical to guaranteeing global food security.
"However, today 30% of the world's agricultural soil is categorized as degraded, with forecasts that this might climb to 90% by 2050," she explained.
According to our analysis, PCS might increase yearly worldwide production of main grain crops by 96 million tonnes, or 4% of present production.
This has a knock-on impact on consumers since it addresses food shortages and price increases.
According to the study, adopting PCS to large-scale agriculture might also assist to prevent climate change.
Every year, more than 7 million tonnes of biowaste end up in landfill in Australia, producing massive amounts of unwanted greenhouse gases and other negative impacts, according to Professor Schmidt.
There are also financial advantages: diverting only 15,000 tonnes of biowaste may save a local government up to $2-3 million per year.
Tony Rossi, a sugarcane farmer in Far North Queensland, claimed his family's firm, V. Rossi & Sons, has been using precise compost for seven years with remarkable results.
We've been able to practically decrease our fertilizer consumption, which is significantly healthier for the environment, while maintaining crop productivity, according to Mr. Rossi.
The PCS research examined over 2,000 examples of compost applications in the agriculture industry from across the world.

Benefits from composting
Any gardener understands that compost is the first soil solution to practically any garden problem, as per Grow Ensemble.
Compost is the most often utilized soil additive for farmers and gardeners alike, for anything from preventing plant disease to correcting nutritional imbalances.
This is due to the fact that compost improves soil structure by contributing vital nutrients, adjusting PH levels, and allowing for greater moisture entry and retention.
All of the beneficial bacteria contained in compost aid in soil aeration and fertilization. In fact, without these tiny guys breaking down nutrients and expanding the surface area of plant roots, most plants would be unable to get the nutrients they require.
Because compost can store 5-20 times its own weight in water, adding compost to the soil increases the quantity of water that can enter the soil.
This is not only good news for the plants; it also means that water may seep all the way down to the impermeable rock layer, where it swells and refills nearby springs, ponds, and lakes.
Water is filtered as it travels through compost, soil, and rock layers on its journey to these water sources.
An astounding 40% of rainfall should flow from these local water sources, implying that compost may play a HUGE role in encouraging rainwater consumption in a region.
Because all water ultimately makes its way to the oceans, the capacity of compost to filter water as it enters the ground implies that the water going into the ocean will be cleaner.
Acidifying fertilizers and other harsh chemicals used in farming are among the most serious polluters of the seas.
Composting reduces the amount of water that runs off into the ocean, reducing the need to use artificial fertilizers and chemical pesticides in the first place.
