Mulch is a protective cover of material that is spread on top of soil.It is usually made out of organic material, like crop waste.Farmers may keep the remains of maize or other crops on top of the soil.This creates mulch on the soil surface.The plant remains help protect the soil against wind and water damage.Mulching is one of the best things people can do for their plants.It also helps keep the soil from getting dry, and reduces the need for watering plants.It also limits temperature changes in the soil.And it stops unwanted plants, or weeds，from growing.

Organic mulch improves the condition of soil.As the mulch breaks down, it provides material which keeps the soil from getting hard.This improves the growth of roots and increases the movement of water through the soil.It also improves the ability of the soil to hold water. Organic mulch contains nutrients for plants.It also provides a good environment for earthworms and other helpful organisms in the soil.

It is easy to find organic mulch materials.Cut­up leaves and small pieces of tree bark can be used.Grass cuttings are also a good mulch for plants. Mulch from newspapers works well in controlling weeds.

The best time to add mulch depends on your goal.Mulch provides a thick barrier between the soil and the air.This helps to reduce temperature changes in the soil. As a result，mulched soil will be cooler than other soil in the summer.In winter, the mulched soil may not freeze as deeply as other soil.The best time is after the ground has frozen, but before the coldest weather arrives.Spreading mulch before the ground has frozen may attract small animals searching for a warm place to spend the winter.Delaying the spreading should prevent this problem.The animals will probably find another place to live.

我国A公司与外国B公司于2003年1月10日签订了购买20万吨小麦的CIF合同。A公司开出信用证规定，装船期限为 2003年2月15～20日，由于B公司租用的甲船开往指定海湾地区港口时由于战争封锁而迟至2月21日才到达装货港，货物于2月22日装好后启运。因而，承运人签发了装船时间与信用证规定不一致的提单。 B公司为这批小麦投保了水渍险。2003年2月28日，甲船在途中遭遇海啸，小麦部分被浸。由于船舶迟延到达，致使目的地小麦价格下降，A公司为尽快处理小麦而大幅降价，承受了巨额损失。请分析案例，并回答下列问题：
