Critics claim that it hinders investments in labor-saving techniques, and leads to unemployment of unskilled native workers. Proponents highlight the contribution of foreign workers to growth, especially in rural areas. This paper investigates whether the inflow foreign workers really affect the demand for local workers in agriculture. We exploit an 8% tax that was assessed on the wages of foreign workers in 2003. If foreign workers are substitutes to local unskilled workers, the demand for local unskilled workers should increase as a result of the tax, and their wages should increase, unless their supply is perfectly elastic. On the other hand, if unskilled workers, foreign or local, are complements to skilled agricultural workers, the demand of the latter should decline, and their wages should decline as well. We found, using a difference-in-difference regression approach, that the wages of local unskilled agricultural workers in Israel increased about 9% following the taxation of foreign worker wages, but the effect is not statistically significant, perhaps because of the small sample size. No changes in wages were found for skilled workers. To conclude, this research provides some support to the hypothesis that there is substitution between foreign workers and local unskilled Israeli workers in agriculture, but this conclusion is not strong enough statistically.","PeriodicalId":7393,"journal":{"name":"Agricultural and Food Science","volume":"15 13 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2020-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84269181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fertilizer and its efficiency play a major role within these practices. It is therefore imperative to maximize the efficiency of applied fertilizer. \u0000 \u0000Omnia has developed an effective, easy to apply, biostimulant coating product called FertiCoat with the main objective of increasing fertilizer use efficiency. Nutrients like phosphorous can become fixed in the soil and become unavailable for crop growth. In low pH soils this occurs due to Al and Fe fixing phosphorous and in high pH soils calcium, magnesium and bicarbonates tie up available phosphorous. \u0000 \u0000To avoid this, FertiCoat™ can be used as a coating onto granular planting fertilizer, Urea or mixed with UAN. It complexes with phosphorous and keep it from being fixed in the soil by unfavorable elements. This makes the applied nutrients more plant available and therefore increases its efficiency and results in increased yields. \u0000 \u0000FertiCoat consists biostimulants like Seaweed, humates, fulvates, Amino Acids and polymers. Besides the benefits from humates and fulvates, it is known that plant hormones and amino acids in Seaweeds will promote plant growth and assist plants to withstand biotic and abiotic stresses. This process indirectly increases fertilizer efficiency as plants will be more vigorous with less fertilizer application. FertiCoat formulation contains these biostimulants in desired levels. \u0000 \u0000Omnia has researched FertiCoat™ over many years and has proven it to be a superior coating product.","PeriodicalId":7393,"journal":{"name":"Agricultural and Food Science","volume":"1 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2020-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86057154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This retrospective study aimed to elaborate factors behind the declining foaling rates in Finnhorses using multivariable logit models. The mating records from years 1998 to 2000 (period 1, n = 5967) and 2002 to 2004 (period 2, n = 5373) originated from the Finnish trotting and breeding association. The over-all foaling rate was 66.6% during period 1 and 62.4% during period 2 (p < 0.0001). Foaling rate for on-site artificial insemination decreased from 70.2% to 64.8% (p = 0.003). The proportion of the most fertile mare groups, 2–9-year-olds and foaled mares, decreased by 8.2 and 7.1 percentage points, respectively. Differences in foaling rates between young and middle-aged mares, and maiden and foaled mares changed from non-significant to significant (p<0.0001) due to the foaling rate decline in middle-aged (p = 0.001) and maiden mares (p = 0.01). The decline in foaling rate was also significant for barren and rested mares (p < 0.05), natural mating (p = 0.01), and book size >68 (p < 0.0001). It was concluded that multiple factors were responsible for the foaling rate decline.","PeriodicalId":7393,"journal":{"name":"Agricultural and Food Science","volume":"20 1","pages":"189-197"},"PeriodicalIF":1.2,"publicationDate":"2020-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87969496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
