2012年4月18日 · The destruction of soil structure impacts plant germination and seedling emergence for both corn and soybean. Soil crusting can also result in poor growing conditions and reduced water infiltration. Soybean seedling emergence can be a …

methods and planting can be beneficial for fields prone to crusting. Fields with a tendency to crust should be monitored closely for emergence after planting and after heavy rains.

A rotary hoe can alleviate emergence problems due to soil crusting. Proper timing, soil moisture, and speed are all critical to realize the benefits of using a rotary hoe. A rotary hoe should be used after determining that a soil crust has actually formed and sealed the soil surface, but before crop emergence. Soybean plants are particularly

If fields exhibit soil crusting, consider a crust-busting operation. With any crust-breaking method, some crop loss is possible. Soil crusting can be broken by working a rotary hoe at a very shallow depth, no deeper than the depth of the crust.

How to break soil crusts: Guide for seeded and unseeded fields. Covers how crusting happens, tools to use, risks and more.

2022年4月20日 · Soil crusting has serious effects on soil productivity and function. It leads to decreased infiltration rate, reduction of soil moisture, increased runoff and reduced groundwater recharge. The hydraulic conductivity of a crust may be a hundred or even thousand times lower than that of the underlaying soil.

Crusting occurs when a heavy rain strikes an unprotected soil surface, breaks down the aggregates, and turns the top layer of soil into a uniform surface seal. This surface crust can be strong enough to inhibit water infiltration, seed emergence and can lead to increased erosion.

2020年6月11日 · These conditions can cause crusting on the soil surface. In this brief overview, I'll discuss how / why crusts form, and how you can respond in the immediate and longer term. At this point in the season, most crops are already in the field.

2021年4月30日 · Fields with a tendency to crust should be monitored closely for emergence after planting and after heavy rains. A tape measure, measuring wheel, or hoop should be used to count emerged plants (Tables 1 and 2). Figure 1. Soybeans emerging through crusted soil (left); Corn leafing out under crusted soil conditions (right).

Soil crusting refers to the formation of a dense, hard layer on the soil surface due to the collapse of surface aggregates during wetting. This layer inhibits water infiltration into the soil and can impede seedling emergence and root growth.
