Download or read book Soil Acidity in Oregon written by and published by . This book was released on 2013 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quick facts: Nitrogen (N) fertilizer application is the predominant management practice that causes soil acidification (declining soil pH). Nitrogen fertilizers that supply N only in the ammonium (NH4) form are the most acidifying (page 6). Crops and varieties differ in tolerance to soil acidity. Recommended minimum pH values for a wide range of crops are listed in Table 9 (pages 18-19). Lime is recommended to maintain soil pH above recommended values. Increased soil acidity can injure plants by a number of mechanisms, including: [1] Increasing the amount of soluble aluminum (Al) and manganese (Mn) in soil to toxic levels (pages 9-11) [2] Reducing the amount of plant-available phosphorus (P), calcium (Ca), and molybdenum (Mo) (pages 11-13)Some legumes are very sensitive to soil acidity because soil acidity inhibits N fixation by bacteria of the genus Rhizobium. These bacteria require high soil levels of Ca and Mo, which are limited at low pH. Under acidic soil conditions, legume roots may have few nodules or their nodules may be ineffective at N fixation (page 13). Information on pH and weed management (pages 20-21) and on soil pH monitoring (pages 7 and 15) is also contained in this publication. Neutralizing soil acidity with lime is discussed in companion publications (page 2).

Book excerpt: The acidity or alkalinity of the soil in which crops grow can influence how well they grow. We measure this characteristic with a pH scale. Each crop has its own ideal pH range. If you want to grow healthy plants, it's important to understand the effect that pH has on the nutrients available to your crop

Available in PDF, EPUB and Kindle. Book excerpt: "Sometimes, soil acidification is necessary for optimum plant growth. Plants with yellowing leaves that do not respond to normal fertilization with nitrogen, phosphorus, and potassium may be suffering from other nutrient deficiencies. The most common solution is to acidify the soil. If you attempt to acidify your soil, keep the following guidelines in mind. [1] Proceed cautiously, as soil pH can be lowered beyond the desired level, especially in sandy soils and small areas. [2] Monitor the change through annual soil testing. [3] Develop a strategy of long-term and short term use of acidifying materials. [4] Keep complete records of the amount of acidifying materials added, the amount of mixing, and the time of year the material was applied."--Summary.
