It hardly ever pays to pasture meadows, except slightly, the first season, and then only when the soil is dry. It is also poor policy to pasture any kind of grass land early in the spring when the soil is wet, because the tramping of animals crushes and destroys the crowns of the plants. After the first year the sward becomes thicker and tougher, and the grass is not at all injured if it is grazed wisely.

The first crop of the season is being cut and stored for winter
The state of maturity at which grass should be harvested to make hay of the best quality varies somewhat with the different grasses and with the use which is to be made of the hay. Generally speaking, it is a good rule to cut grass for hay just as it is beginning to bloom or just after the bloom has fallen. All grasses become less palatable to stock as they mature and form seed. If grass be allowed to go to seed, most of the nutrition in the stalk is used to form the seed.

Hence a good deal of food is lost by waiting to cut hay until the seeds are formed.
Pasture lands and meadow lands are often greatly improved by replowing and harrowing in order to break up the turf that forms and to admit air more freely into the soil. The plant-roots that are destroyed by the plowing or harrowing make quickly available plant food by their decay, and the physical improvement of the soil leads to a thicker and better stand. In the older sections of the country commercial fertilizer can be used to advantage in producing hay and pasturage. If, however, clover has just been grown on grass land or if it is growing well with the grass, there is no need to add nitrogen. If the grass seems to lack sufficient nourishment, add phosphoric acid and potash. However, grass not grown in company with clover often needs dried blood, nitrate of soda, or some other nitrogen-supplying agent. Of course it is understood that no better fertilizer can be applied to grass than barnyard manure.
