土壤测试和组织采样是发展的关键optimal crop nutrition program。如果您不知道您的土壤包含哪些营养素，并且您不知道植物是如何或未吸收的，那么您如何知道您是否提供正确的营养素？土壤测试和组织采样采取了这一过程的猜测。让我们与您审查您的土壤测试分析，以帮助为您的运营制定正确的作物营养计划。
Soil testing is the first step in determining the optimal nutrition program. A soil test can tell you a lot about the soil conditionsat your orchard,包括营养水平、pH值、饱和度的基础,organic matter, and cation-exchange capacity (CEC). All of these factors play a role in how your plants absorb water and nutrients, whether those nutrients are usable in the soil, and the biological activity determining the soil health.
A soil test can answer a lot of questions you may have about yourfruit, nut, or vinecrops.在树木或葡萄藤中，养分缺陷会导致叶片在边缘围绕叶子变色。随着树木努力分配不足的营养，新的成长和芽将减少。在某些情况下，例如苹果缺钙，水果会出现变形或变色。土壤分析可以告诉你你的果树缺失了什么。With this information, you can correct the problem and stop it from happening again. A soil test can also tell you what nutrients or additives can help you increase yield. For example, low levels of some micronutrients can decrease utilization of other macronutrients. The crops will still be productive, but not as productive as they could be.
Benefits Soil Testing
- Reveal nutrient deficiencies causing stunted growth
- Show biological activity and the impact on nutrient retention
- Show CEC, soil quality, and possible improvements
- Show ways to increase yield
How do I gather a sample for a soil test?
Gathering samples for soil testing isn’t complicated, but it must be done with care. This ensures your soil test accurately represents the area you’re testing.
Follow these instructions to get the most accurate soil test possible ›
把单独的土壤样本区域显示阴极射线示波器p damage, different soil types, or different water absorption patterns. Each composite sample should not represent an area larger than 20 acres.
Place soil samples in a clean plastic bucket that is not used for any other purpose. Metal buckets and residue on the bucket will corrupt the sample.
Wait for the results!
Soil testing will reveal the health and nutrient profile of the soil, but it won’t show how plants actually absorb these nutrients. A number of factors can affect nutrient absorption in plants, and this won’t be clear from a soil sample. This is where tissue sampling comes in. A plant tissue sample will show what nutrients the plant has absorbed and the movement of nutrients throughout the plant.
Trees, vines, and other permanent crops use different nutrients in different ways. Some of these nutrients are mobile within the plant, so the nutrients will be redistributed to where they are needed most. Deficiencies in these nutrients can slow the tree’s overall growth and weaken its health. Other nutrients are locked into place, so they cannot be redistributed to blossoms, fruits, and seeds. With a tissue test, you can see underneath the visible effects, which can be difficult to interpret, and see how your crops are affected.
Benefits of Tissue Sampling
- Reveal issues with nutrient absorption
- Show diseases or fungus affecting plants
- Show nutrient movement and sugar processing
- Show stunted root growth
How do I gather a sample for a tissue test?
抽样方法取决于工厂的年龄和类型。。不同的树木可能需要略微不同的收获方法。一般来说，在夏季中期收集新芽的健康叶子。It’s a good idea to take at least three samples from each part of the grid or zig-zag.
Be sure to collect clean plants without mud splash, and place them in the sample bag or in a clean plastic bucket. Mud, residues, or metal buckets can disrupt the sample.
Mail the tissue samples using the bag and address provided.
Wait for the results!
