Living mulch builds soil, profits

Compost functions on garden or almost any farm except like mulch — it is alive. No, it’s not from the horror movie; living mulch is a method farmers can use to gain the dirt and both gains. Scientists at the University of Georgia are making it sustainable and more efficient while the system’s existed for some time.

Compost functions on garden or almost any farm except like mulch — it is alive. No, it’s not from the horror movie; living mulch is a method farmers can use to gain the dirt and both gains. Scientists at the University of Georgia are making it sustainable and more efficient while the system’s existed for some time.

The living compost program uses a recurrent plant between rows of crops. In their work, the Georgia investigators used clover between rows of corn. White clover may furnish the harvest with nitrogen fertilizer and is a legume. The notion is that every planting period, farmers remove a portion of the clover and plant that the row crop. Though the corn develops, there’s then clover between the pops serving as living mulch.

Ideally, after the corn has been harvested, the clover takes on the area and the cycle starts again the next season, with the farmer eliminating portions of this clover. This practice isn’t ideal and the living mulch fails to. The scientists at Georgia have been currently working to change that.

“We chose white clover especially to use as living mulch as it has the ability to regrow and revive itself when the conditions are right, and to perpetuate itself from year to year,” says Nicholas Hill, lead researcher. “We needed to start defining what the conditions were in the standpoint of agricultural practices that could help the clover regrow year-to-year into a corn manufacturing system.”

The scientists largely looked at two different factors broad of a group of clover to spray how broad to create the rows of corn and then with herbicide. They found the perfect group to spray with herbicide has been 20 cm (8″) wide and the perfect harvest row width was 90 cm (36″).

“The entire idea is to hit a balance between getting the clover be in a position to reestablish, preventing it from outcompeting the corn, and having the ability to generate enough corn to create a profit,” explains Hill. “In broader proportions, more light disrupts the corn to get to the clover after in the year and it can persist somewhat longer, while at narrow rows it does not. And then if we spray too much to plant the corn, then it won’t have the ability to reestablish after harvest. But should we spray too small it will outcompete the corn at the pops.”

Getting this balancing act right can be extremely helpful to the cover crop (that the clover), the row harvest (the corn), along with the farmer. The shading characteristics of the corn above the clover control the nutrient release of the clover to the corn when spacing conditions are perfect. By decreasing its leaves onto the 12, the clover responds to shade. Those decompose and add nutrients to the ground that the corn can use. This is described by Hill as a capsule of fertilizer. That means less fertilizer .

What’s more, the clover is prevented by the perfect blend of conditions however does not do much harm that when the corn has been gone the clover can not take the area over following the period. The researchers’ aim was to get up to clover cover that is 100%, plus they could attain that.

The researchers found the living mulch system does create a corn than traditional methods. On the other hand, the reduce production is outweighed by the cost savings in the system. Hill reports that they implemented 75-80 percent less herbicide to the area, as a result of this clover outcompeting dangerous weeds, and less nitrogen fertilizer due to the nutrients that the corn gets out of the clover. So that the farmer can wind up earning more cash.

“Living mulch is the best thing since sliced bread,” Hill says. “We are seeing a great deal of benefits. It can benefit the dirt, the corn, and the company, therefore it is really a win-win-win situation we are attempting to scale to work with. We are starting to research and document all of these benefits and will continue to carry out research on living compost”
