Soil Amendments and Organic Materials

图片
Soil amendments can improve the overall physical properties of soils. The amendments are mixed in with the soil, and then mulch is usually placed over the surface. The soil can then receive nutrients through the amendments. When choosing the best choice for soil amendments, they should be ones that can increase water and the capacity to hold nutrients. It will improve the overall aeration and water infiltration through the soil. Having wood products in the soil can tie up any nitrogen that is in the soil. One important tip that many people should know is that when you go to choose and use biosolids, you want to choose Grade 1 for the ultimate performance for your soil. A soil amendment is any solution or material that is added to soil in order to improve the physical properties of the soil, such as water retention, water infiltration, permeability, drainage, structure, and aeration. The goal of the soil amendment is to provide a better and more nourishing environment for roots. For a s...

Why does crop quality decline after continuous cropping?

图片
In some plants,stems and leaves appear scorching and shrinking,and some even die.Some pest structures also change.This is what the performance of continuous cropping obstacle in different crops.  The reasons are generally the following aspects: 1.Continuous cropping causes symptoms of deficiency in soil Field crops have a long reproductive cycle.The vegetable has a short growing period and a high multiple cropping index. However,whether the same crop or vegetable is grown on the same land for a long or short period,it will absorb more elements, and the element in the soil will be in short supply.Some will also lead to changes in the pH of the soil,and the availability of certain elements in the soil will also decrease.As a result, some cotton will have potassium deficiency,some cabbage will have calcium deficiency, and some will suffer from Zinc Magnesium deficiency. 2.Serious harm of pests and Pathogens in soil The common diseases in continuous cropping fields a...

Do you know how to control powdery mildew?

图片
Most of us are familiar with powdery mildew,from field to greenhouse, from vegetable garden to orchard garden,it can be said that it appears in most places with crops.Once the crop is infected with powdery mildew,it is rapidly developed and difficult to control, often causing serious problems. powdery mildew Right now at the time of from spring to summer, the temperature rises rapidly everywhere, the temperature difference between day and night is relatively large, and the dry and wet changes in the cultivation environment are relatively frequent, which is extremely conducive to the occurrence of powdery mildew, so we must pay close attention to prevention work. In general, the genus of powdery mildew on different plants is different. Most powdery mildew pathogens can infect only one host plant. Only a few powdery mildew species can infect a variety of host plants. However, regardless of the genus, the resulting diseases are similar in their basic symptoms. ...

What's key problem about soil,Soil hardening/acidification?

图片
In this article,We will know the essential problems in soil,all of them can not be neglected.Now let's go into these problems. More info of Soil problems  Read more How to solve the these problems  Read more   Soil hardening   Soil hardening means that soil structure is destroyed,the tillage layer is hardened,and the air permeability is poor.It seriously affect the normal growth of crop roots. Main reason The input of organic fertilizer is seriously insufficient: the content of organic matter in the soil is low and the structure is deteriorated, which affects the activity of microorganisms, thereby affecting the formation of soil aggregate structure and leading to soil hardening.Long-term excessive application of chemical fertilizers: It destroyed the soil structure, and soil organic matter could not be replenished in time,causing  soil hardening and cracking.Agricultural measures such as repression, plowing, and watering...

Dora Rootguard good partner of humic acids to make formulations

图片
For the solution(Trichoderma harzianum + humic acids)  Effectively increase soil condition , prevent crops diseases and promote long-term growthInhibite soil-borne diseases , prevent continuous cropping obstacles,improve yields effectively Usage of chemical pesticides can be reduced significantly One plus one is much greater than two  (1+1>2) Both of humic acids and trichoderma harzianum are environmental friendly and follow international trend in the field. Below are trial reports of Dora Rootguard + Humic acids applied on Cayenne Pepperannuum and Nectarine  Before germination period,We apply humic acids with NPK(15-15-15) in soil. Conclusion of the solution(Trichoderma harzianum + humic acids)     Improve utilization rate of fertilizer,and reduce usage of chemical fertilizers. Meanwhile,it promotes crops’ roots growth,improve soil structure and preserve moisture and fertility. After application of Dora Rootguard,output inc...

What To Do If Your Soil is Too Alkaline

图片
In A Nutshell Your best option is to add organic matter and grow plants that do well in alkaline soils. The Whole Story Technically, all soils with a pH higher than 7.0 are alkaline, or "sweet," but most garden plants tolerate a pH up to about 7.5. Alkaline soils are generally composed of basic (high pH) parent materials such as limestone (calcium carbonate). High-pH soils are more prevalent in arid climates, because rainfall does not leach the calcium and other basic materials out of the soil. Soil pH affects nutrient availability for plants, and in soils with a pH over 7.8, iron, zinc, and phosphorus deficiencies are common. Lowering soil pH is a slow and challenging process. "The truth is, lowering soil pH is hard, because the limestone in the soil continually dissolves," says Jessica Davis, Ph.D., a professor of soil science at Colorado State University. Davis recommends getting your soil tested to determine its pH, lime content, soil texture, and...
