A researcher took soil sample from a plot 50 m × 40 m and after the appropriate tests came up a recommendation for NPK fertilization at 80 kg N/ha, 100 kg P2O5/ha and 50 K2Okg/ha. Calculate the amount of urea (46% N), triple superphosphate (45%) and potassium sulphate (48%) required to supply the required nutrients.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.
