Application of leather shavings to agricultural crops may represent an effective disposal alternative, providing a good source of plant nutrients. The effect of shavings, compost obtained from them, a mixture of shavings and compost, manure and chemical fertilizer on maize was studied in field and in controlled environment trials. Shavings, compost and the mixture of shavings and compost were applied at 15 and 30 t ha-1 dry weight. Shavings at both rates increased grain dry weight and N uptake by over 45% compared to fertilized control, owing to the high release of available N. Conversely, all other amendments did not produce any significant increase. The uptake of Ti and Cr by maize plants was very low, never exceeding 80 g Ti ha-1 and 14 g Cr ha-1, and was not modified by all amendments. Leached N increased by 17 kg ha-1 with SC15 and by 30 kg ha-1 with S15, compared to control. Doubling the level of shavings and of the mixture of shavings and compost increased leached N by over 20 kg ha-1.
