880 EXPEEIMENT STATION RECOED. 



cwt. nitrate of soda, 4 cwt. basic slag (liigh grade), and 2 cwt. kainit produced 

 practically the same increase in yield of hay and at almost the same cost. In 

 using seaweed for potatoes it was shown that " weight for weight, seaweed 

 seldom produces as heavy a crop of potatoes as does farmyard manure ; muriate 

 of potash generally has less effect when used with seaweed than when applied 

 with dung ; seaweed gives the best results on light soils and, possibly, in a dry 

 season." 



In experiments with mangels the use of 20 tons of barnyard manure per acre 

 was more profitable than a dressing of 15 tons. Adding 4 cwt. superphos- 

 phate resulted in an average profit of 6s. 6<1 (about $1.58) per acre, while 

 also adding 2 cwt. of sulphate of ammonia resulted in an average annual 

 profit of 3s. 6d., and either 2 cwt. or 4 cwt. of kainit in annual profits of 16s. 6d. 



Plant breeding in Sweden, H. H. Nilsson {Jour. Heredity, 5 (WW, No. 7, 

 pp. 281-296, figs. 7). — This article describes the old method of "selection in 

 mass " and the modern one of " pedigreed culture ", and relates the achieve- 

 ment obtained at the Svalof Institute in the production and introduction of 

 improved strains of cereals, legumes, and forage plants and the influence of 

 this work on plant breeding in general. 



A study of root systems of plants in pure and in mixed seedings, C. Kbaus 

 (Fiihling's Landw. Ztg., 63 (i9i^), Nos. 10, pp. 337-362, pis. 5; 11, pp. 369-383; 

 12, pp. 401-412). — The author gives results of his study at Munich in regard to 

 the length, size, volume, and spread of root systems of cereals and legumes 

 planted in both field and pot cultures, in mixtures, and in single varieties. 



It seems from these results that an intimate knowledge of the habits of 

 growth of root systems of agricultural plants will greatly enable the grower to 

 space plants to better advantage, and to sow such mixtures that the soil volume 

 wUl have a better distribution of roots and thus allow of a more intensive 

 method of cultivation. 



Inoculation of legumes with special reference to high moorland, A. 

 Densch {Mitt. Ver. Ford. Moorkultur Deut. Reiche, 32 {1914), Nos. 10, pp.

 subject.

Cultivation and management of moorland pastures and meadows, M.

The seeding of meadows and pastures, C. B. Hutchison {Missoui-i 8ta. 

 Circ. 68 (1914), pp. 259-265). — This circular discusses the value and uses of 

 nurse crops, timothy, red and alsike clovers, and orchard grass, and fertilizing 

 meadows and pastures, and suggests several grass seed mixtures. 



The favorable depth for grass seed, G. Richtee {Mitt. Ver. Ford Moorkultur 

 Deut. Reiche, 32 {1914), No. 12, pp. 270-276).— Results here reported show 

 much better yields after harrowing and rolling than after rolling only.
