True or False: In finer textured soils, the maximum safe limits for seed-placed fertilizers are slightly lower than those for coarser textured soils.

In finer textured soils, it is indeed true that the maximum safe limits for seed-placed fertilizers are lower than those for coarser textured soils. This phenomenon occurs because finer textured soils, such as clay or silt, tend to retain more moisture and nutrients, which increases the risk of fertilizer injury to germinating seeds. The smaller soil particles create a more compact environment that limits air and root development for seeds.

Unlike coarser textured soils, where larger particle sizes allow for better aeration and drainage, finer textures can lead to higher concentrations of fertilizers around the seed. If the fertilizer concentration is too high, it can cause toxicity to the developing plant, leading to poor germination or stunted growth. Therefore, the answer is true as finer textured soils warrant more cautious application of seed-placed fertilizers to avoid any detrimental effects on crop establishment. This principle is essential in nutrient management practices to ensure optimal crop health and productivity.
