阿尔巴尼亚人. According to the latest cycle (the fourth) of the agrochemical study, the arable Albanian sols contain 1,395 mg P/100 g of soil on the average, and are divided into the following groups: 32,6 per cent are poor, 41,3 per cent medium and 26,1 per cent are rich in this element. According to the above division of arable land into three big groups, depending on the average annual growth, it is needed a positive balance of 4500-8500 kg P205/ha for the first group, of 1300-3300 kg P205/ha for the second, and less than 1000 kg P205/ha for the third, to bring about a further change in phosphorous content of 1 mg/100 g of soil.
