Plant nutrient dynamics in decomposing needle litter were measured during a 5-year period in a Scots pine forest in central Sweden. As seen over the whole 5-year period, the nutrients were retained (to a litter weight loss of about 75%) in the order Mn < Ca < K < Mg < S < N < P. During the first 1.5 years there was a net increase of N and P whereafter a net release took place. A similar but less pronounced development could be seen for S, whereas Ca, K, Mn, and Mg were released from the start of the incubation. It is suggested that P was the most limiting element for microbial activity during this first phase. There appeared to be only little initial leaching from the litter and the different behaviours of the elements could largely be explained by their concentration in litter in relation to the needs of microorganisms and to their solubility. K and Mg were the elements that were released at rates most similar to organic matter weight loss.

The litterfall under different aged (sapling, pole and mature) Chir pine stands were studied at two sites viz. Nauni and Moti Kona (Kasauli) having altitudes 1250-1275m and 1720-1745m amsl., respectively in the mid hills of Himachal Pradesh throughout the year. The litter comprised of needles, twigs / branch and bark under sapling and pole stands of Chir pine whereas cones were also the part of the total litter production under mature stands at both sites. The litterfall was maximum under mature stands followed by pole and sapling stands at Site-I whereas it was maximum under pole stand followed by mature and sapling stands at Site-II. The needles had the maximum share (93 to 99%) in the total litter under all the Chir pine stands. The average annual litter production under sapling,pole and mature stands was 64.68, 73.49 and 102.01 q/ha, respectively at Site-I whereas at Site-II, it was 33.34, 55.20 and 37.84 q/ha, respectively. The needle fall was maximum in summer months i.e. April and May under all the Chir pine stands at both the sites and it was about 60 to 70 per cent of the total litterfall of the year. The information generated from the present study may be beneficial for devising management strategies for Chir pine needle litter and can also help in making the strategies for fire control in Chir pine forests of mid hills of Himalayas.
