收藏:土壤测试
准确了解土壤测试所需的土壤!一切都始于土壤。无论您是园艺10平方英尺还是耕种数千英亩的土地,智能种植者都知道,通过对土壤优势和劣势的特定诊断,土壤测试以提高生产率和有针对性的施肥为可能。无论您是发送土壤样品进行专业实验室土壤测试,购买DIY土壤测试套件,还是使用专业仪表,以良好的土壤开始!
了解有关土壤测试的更多信息现场测试工具可以充分利用一些最好的科学。大多数这些工具和测试套件的一般原理是测量解决方案的特定属性。解决方案是通过将土壤,肥料,有机物(叶子,堆肥等)与蒸馏水结合在一起而制成的。一旦知道土壤和植物的特性,您将获得有关您的农作物和土壤的健康,生育,成熟和活动的新信息。下面的词汇表将帮助您了解这些设备可以测量的基础知识以及该知识如何为您提供更绿色的拇指。
- ph- 酸度或碱度的测量范围从1(最大)到7(中性)至14(最多碱性)。您的土壤可能在5至8.5范围内。 In soil, pH extremes limit biological activity, humus formation, and plant growth. Frequent monitoring is essential, as soil pH changes rapidly during fertilization, irrigation, and even the phases of the moon. Effective pH monitoring of spray solutions will maximize nutrient uptake in foliar feeds.
- EC- 土壤的电导率测试提供了大量信息:粒度和纹理,排水,阳离子交换能力[CEC],以显示粘土和有机物的百分比,表土深度,孔隙率,盐度和温度。
- ERGS - Energy Released per Gram of Soil, as defined by Carey Reams. ERGS represents the amount of energy available to the growing crops and microorganisms. For example; overall reading above 1,000 generally indicates a salt problem, energy loss and waste, and increased potential for root burn. Overall levels below 200 indicate little or no crop growth is occurring. Late-season crop finishing is directly correlated to the ERGS level.
- TDS- 总溶解固体。液体中包含的所有有机物质和非有机物质的组合含量的表达。
- ORP - Oxygen Reduction Potential or available oxygen. Oxygen availability is crucial to the plant’s uptake ability. Based on ORP reading, available oxygen can be easily adjusted using hydrogen peroxide. This definitely enhances the effectiveness of foliar feeds by increasing plant ability to absorb them. ORP and pH readings together provide an “rH value,” which is used to diagnose the biological condition of your soil.
- Rh - Redox Value A soil rH below 25 indicates low oxygen, limited biological activity, and a consequent lack of humus-building. A soil rH over 29 indicates too much oxygen, resulting in oxidation of organic material and loss of carbon to the atmosphere, limiting nutrient availability to the crop. rH value is derived from the ORP and pH readings.
- brix - High Brix is a plant, not a soil, reading. It indicates adequate nutrition and is an excellent measurement of fertilization success. Plants with high Brix (reading above 12) sugar content are generally healthy. Used to measure sugar content (Brix) of fruits to determine maturity. Also used to monitor the Brix in plant tissue (leaves and stems) throughout the season.
- 参考解决方案- 大多数仪表不包括在校准仪表中,尽管它们是必需的。对于pH,7.0溶液是用于主要校准的解决方案。如果始终需要以下pH 6.0的准确读数,也建议使用4.0溶液。为了获得最佳校准和准确性,请同时使用7.0和4.0参考解决方案。
购买我们有机种子的原因
无合成农药生长
传统上种植的种子来自在田间生长的植物,甚至比食品作物更长,并且可能会有更多的接触合成农药和杀真菌剂,以使它们成为种子生产者的可行性。无需使用合成农药和杀菌剂而生产有机种子。
