Soil salinity is important in agriculture because salinity reduces crop yields by reducing the osmotic potential, making it more diffi cult for the plant to extract water, by causing specifi c-ion toxicity, by upsetting the nutritional balance of plants, and by aff ecting the tilth and permeability of a soil. A discussion of the principles, methods, and equipment for measuring soil salinity is presented. The discussion provides a basic knowledge of the background, principles, equipment, and current accepted procedures and methodology for measuring soil salinity in the laboratory using electrical conductivity of aqueous extracts from soil samples and measurement of total dissolved solids in the saturated soil extract. Attention is also given to the use of suction cup extractors, porous matrix or salinity sensors, electrical resistivity, and electromagnetic induction to measure salinity in soil lysimeter columns and small fi eld plots (<10 by 10 m). Land resource managers, producers, extension specialists, Natural Resource Conservation Service fi eld staff , undergraduate and graduate students, and university, federal, and state researchers are the benefi ciaries of the information provided.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2017-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2136/MSA2015.0039","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42599266","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study deals with the combined effects of water application methods and tillage practices on water and salt distributions, runoff production, and soil loss in a field irrigated with moving irrigation systems (MIS). An experiment was conducted in a cotton (Gossypium hirsutum L. cv. Sivon) field at Hazorea, Israel, where the main soil type is vertisol (Typic Chromoxerets). Sprinkling (SP) and flooding (FL) MIS, and conventional (CT) and microbasin (MB) tillage, were compared in terms of runoff and soil loss from runoff microplots (5 m 2 ), soil water content and salinity distribution with depth, yield, and plant height. Under SP conditions, no runoff and soil loss were obtained for either tillage practice. In the FL/CT treatment, the mean runoff and soil loss were about 25% of the irrigation water and 0.59 kg m -2 . The FL/MB treatment reduced the runoff and soil loss to 5.8% and 0.02 kg m -2 , respectively. The soil water contents in the SP treatments were generally lower than in the FL treatments, especially in the 0.1-to 0.6-m soil layer. No significant differences in the soil salinity, plant height, and seed-cotton yield were observed between the treatments. Microbasins tillage reduces water losses under flooding MIS to a point where they become practically similar to those obtained under sprinkler MIS. It can potentially lead to lower water losses if the microbasins storage capacity is matched to the water application rate, to avoid runoff.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":"67 1","pages":"852-858"},"PeriodicalIF":2.9,"publicationDate":"2003-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67757804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Soil Mn nodules collected from Typic Hapludalfs in Okinawa Island, Japan, were dissolved using successive NaOH, hydroxylamine hydrochloride (HAHC), and dithionite-citrate-bicarbonate (DCB) reagents at various temperatures. A test sample was prepared by mixing synthetic Bs, Lp (USNM#8811), natural gibbsite (Gb) and goethite (Ge), and soil clay containing kaolinite, illite, and vermiculite-chlorite intergrade mineral and used as a comparative standard. The NaOH treatment was able to dissolve kaolinite and Gb, concentrated the Bs, Lp, and Ge in the comparative sample. The HAHC treatment at 25°C effectively dissolved Bs but Lp and Ge remained undissolved. A subsequent extraction with HAHC at 60°C dissolved Lp without disturbing Ge. Finally, the DCB treatment was able to dissolve Ge. Thus, extraction with HAHC at 25 and 60°C were useful in distinguishing Bs and Lp respectively from Fe oxides minerals. The proposed method can also be applied to distinguish Mn, Fe, and Al oxide minerals in Fe-Mn nodules of natural soil.","PeriodicalId":22142,"journal":{"name":"Soil Science Society of America Journal","volume":"67 1","pages":"837-843"},"PeriodicalIF":2.9,"publicationDate":"2003-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67757736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
